Your brakes example is typical of someone who was never taught to work on their own vehicle.

Others have pointed out that it is not dangerous, so I’ll point out that it is emensely rewarding to do this kind of work yourself. Enlist a competent buddy and give it a try.


Really? Years back I had the brakes completely fail on a classic Mini I'd worked on because one of the pipes wasn't fully tightened and all of the brake fluid pissed out the first time I applied the brakes. Thankfully I managed to grab the handbrake use that to stop (the Mini handbrake is cable powered and independent of the hydraulic system).

Do modern cars have anything to mitigate this?


Pre-modern cars have something to mitigate this, testing your brakes more than a single pedal push before you go out on the road. Kind of sounds like you didn't even bother to bleed the lines which is also asking for a heap of trouble even if you managed to properly repair the entire braking system.

I've worked on the brakes on multiple cars and never once took one out for a test drive without triple-checking that I didn't make some stupid mistake that would put other people in danger.

Don't get me wrong, I had a couple cars with dodgy brakes over the years but always made sure they were good enough at the time I was driving them -- had this '53 Dodge that I had to bleed the brakes every time I wanted to take it out for a spin because the wheel cylinders were pitted and slowly leaked but always made sure to do a proper job because other people's lives were at risk too.


My understanding is that not all classic Minis had dual circuit hydraulic brakes. So if you have one of the originals with a single brake circuits, any leak means you will fail to stop (if fitted with drum brakes, stopping was doubtful anyway)


He wouldn’t/couldn’t have swam continuously for 72 hours. He would have floated, treaded water, etc. the wetsuit kept him warm.


Did anybody read the article?? One of the most important factors was staying in the fetal position- he even lost consciousness at times and was saved by a floatation device that kept his head above water.


In boats we have had autopilot for decades. It takes the boat on a straight path to a point via GPS only. You must pay attention and correct course for obsticals in your path. Simple, logical and efficient.

I believe it's a deferral on paying taxes on your 'earnings' from the options purchased, not a deferral on exercising.


IMO, making it easier to drive will increase the number of people who commute. There isn’t enough space to add extra lanes to facilitate the increase in traffic these vehicles will cause. I think we should be working on other transportation problems.


Agree 100%. Making driving easier and more convenient isn’t going to solve our transit problems, it’s going to make them worse. Just look at what is happening with ridesharing services - people choosing them over public transit because they make it a little easier to get from point A to point B. The same thing will happen with autonomous vehicles. I agree that there are benefits for the last mile of the suburbs and countryside, but not in areas that could be better served by mass transit and an ounce or two of tolerating the inconvenience.

Some people will claim that the fact that autonomous vehicles can drive closely to one another will reduce congestion. Yeah, if they are the only cars on the road. I don’t see a future anytime soon in which 100% of our population (or even 80%) will be so enamored with autonomous vehicles that they’ll be wanting or willing to give up driving and car ownership.


This isn't really true. For example, I'm going to see a show in SF and taking the Caltrain only because I can Lyft the remaining distance to the venue. Otherwise I would be driving the whole way.


That's probably what was meant by "last mile":

>"...I agree that there are benefits for the last mile of the >suburbs and countryside, ..."

:)

A good solution would be great public transportation and ride sharing working together. It doesn't have to be black or white.


I don't agree. Self-driving cars can solve the "last-mile" problem and I am convinced that they are actually the most important tool for building the 21. century public-transportation.

At least in Europe, public transportation is usually pretty good already and there is a lot of capacity left unused because while trains are going relatively deep into the suburbs and countryside, they only serve those living next to it. Self-driving cars could unlock this potential.

Edit: If you look at for example Munich, I don't think self-driving cars will be a challenge to the public transportation inside the city. But they can help getting completely rid of your own car (or alleviate the desire to buy one).


I like this point. My concern is people using autonomous vehicles to commute.


Cheaper, more efficient and better "last mile" solutions: Bicycle share in protected bike lanes, a pleasant walk.


Generally yes, but you still need a solution for the cases not covered by those, like my 84-year-old neighbor who has kidney dialysis twice a week, and who can't really walk more than a few meters anymore.

The trick is to cover every case but nudge people to take the less demanding option if they can. Easier said than done, though.


At the same time, self driving cars could use the roads more efficiently (once they make up most traffic).

I think you're generally right though. I know if I had a self driving car, I'd move further out of the city. If it adds to my commute time, I won't care if I can do other things while I commute (work, read, write, sleep, etc...).


At the same time, self driving cars could use the roads more efficiently (once they make up most traffic).

That last step is quite a doozy though.


They could do it sooner with dedicated lanes that run faster / more efficient, just like HOV lanes today.


self driving and electrification will explode the number of vehicles on roads but with proper management the increase in mobility would be good for society and especially those who cannot drive or reach other forms of transportation.

I do question the idea of trying to use autonomous cars in cities first when limited access roads are a far better choice for early uses of the technology. Giving new purpose to HOV and Express lanes would be far simpler to develop for and easier for governments to accommodate. The idea of entering an limited access road or any road with a protected lane and being able to let the car do the driving has many advantages to both road use and over all trip times plus the previously mentioned ease of implementation


and I suspect that fully autonomous electric cars might just orbit the city if parking/charging spaces are not avaible.

When I worked for an Arab Company in London one of the messenger "boys" jobs was to when a traffic warden was spotted to drive the senior directors cars (seriously stepped on mercs and bmw's with the after market armour packages ) around the block few times and park it back outside the office :-)


As a father, I agree completely, and think you shouldn't have been down voted, so here's an upvote.


Does anyone else think he shouldn't have given the attacker all that information about his defenses?


If I were an evil VP tasked with creating this loop hole, I'd tell my project manager we needed a configurable system that let us control emissions for our intneral testing environments or some other plausible and legal requirement. I'd keep the knowledge of the system obscure and communication between dev, testing and deployment sparse. I'd then have only one person change the configuration before deployment. I'm sure it could be arranged so that no single engineer would realize that evil configuration was released and if they did, it could be excused as a mistake.


If I was an evil VP, I would give my eningeers the incentive to do something without giving them a direct order. So, you might tell them: If you can improve gas millage by X% you get a huge bonus and I don't care how you do it.


This is how modern companies break the rules. Management doesn't break the rules, either overtly or covertly. Management scrupulously follows the rules, while placing requirements on their workers that can only be met by breaking the rules.

Want your workers to work more, but you don't want to pay overtime, or you run into trouble with regulations about consecutive hours on the job? Just bump up how much work they have to get done, threaten to fire low performers, and make it clear that under no circumstances is anyone allowed to work overtime. Your workers will start working off the clock, and better yet they'll hide it from you, so you can legitimately plead ignorance if the law comes after you.

Want to cut corners on safety to save money? Tell your people that safety is the top priority but you need to see an X% reduction in costs, and it works itself out. They may fudge or falsify metrics, but if you're really lucky they'll find loopholes in the metrics instead.

(I have a friend who worked at a warehouse and fell victim to this. They were officially big on safety, which included bonuses for everyone if they went a certain period of time without any safety incidents. Unofficially, this meant that incidents wouldn't be reported unless it was unavoidable. The one way to ensure that an incident had to be reported was to see a doctor for your injury, so people were heavily encouraged to wait to see if they got better on their own before they got medical attention, which often made things much worse. I'm sure upper management's metrics looked great, though.)

As an added bonus, this sort of thing gives you a lot more control over workers. If you want to get rid of a troublemaker, do a little digging and you'll surely discover that they're violating safety rules or working off the clock or whatever. Everybody is, but selective enforcement is a wonderful thing.


This is also how we end up with "crazy" regulations. Case-in-point: nuclear waste handling. Engineers create complex six-sigma safety plans which are then slowly eroded as the regulations and safety protocols are wacky overkill, right?

The WIPP nuclear isolation site had a 15 year run so management began to cut corners. Then three unlikely events all lined up and nearly got people killed. It started with a truck catching fire, which prompted operators to bypass the HVAC's filtration system. They stopped the bypass for a few days to perform maintenance on the only underground radiation detection unit. That unit gave a false alarm during testing, but was fixed and placed back into service so they started ventilating again. Then a cask was breached ~midnight because someone upstream had used organic kitty litter instead of clay kitty litter. The operator assumed it was a false alarm due to the previous false positive and kept things running. It wasn't until the next morning that they realized they were blowing radioactive particles above ground.

Had management kept maintenance up, enforced protocol, or done more than the absolute bare minimum (i.e. installing multiple underground radiation detection units) US tax payers could have avoided paying $500 million dollars. And this isn't a one-off thing, there are dozens of instances just like this where the US dodged a bullet.

What a fascinating DB you linked to. I'd never known these types of things were public or common.


Seems like the "organic" fad was the problem


The problem was substituting an unsuitable material because of mistakes when revising procedures and insufficient review of the revisions. The fact that the mistake involved an "organic" product is coincidental.


You have made some very strong points - thanks for summarizing it together.

I would like to ask: What do you think should an ordinary employee do when they see a behavior like you describe from their management? How to efficiently protect themselves (and their colleagues) from this kind of treatment?


I've just observed this, not experienced it, so I'm not sure. It's far easier to see the problem than figure out a solution!

Much will depend on your job prospects and financial position. If you're a fancy programmer type who's constantly bugged by recruiters, move on until you find an ethical company. If you need this job to eat, you'll have to be a lot more careful.

In general, I'd say:

1. Point out the impossibility of the requirements to management. Gently if need be. It's possible they don't realize what they're doing.

2. Contact the local department of labor or whatever regulatory agency would be interested in what's going on. They may be able to take action if management is pushing violations in a quiet way like this. If not, they may be able to at least take action against the workplace if people have started breaking the rules.

3. If you can afford to risk the consequences, follow the rules as much as you can. Don't work off the clock, don't break safety rules, etc. If being fired will make you homeless then maybe this isn't an option.

4. Document everything. If regulators weren't interested originally, they may be interested once you can show a pattern. Upper management may be blissfully ignorant, and you may be able to get them involved once you can show them what's going on. Whatever happens, if things come to a head then it will probably be useful to be able to demonstrate that this wasn't your own doing.


The list of 4 items is excellent. Under no circumstances should you act in an insubordinate manner until you've exercised other channels of communication. Acting before things get too far is the easiest remedy.

I'd recommend the following order of operations:

Convey concern over associated risk to your immediate manager. Verbally first during the meeting, switch to written (email, a paper trail of opposition) if no action is taken.

When documenting the paper trail, simply reference meetings which you voiced opposition. Your notepads should also be able to back up the talking point you're referencing.

Being asked to briefly switch hours or work late is often listed in your job description so stopping suddenly at 5p can be considered insubordinate. Time should be compensated in a time off or paid OT arrangement promptly. If your verbal requests go without action, again, switch to email.

Simply documenting the events as they occur makes it easy for when you need to go above your immediate supervisor ( more senior manager, corporate hq, department of labor) for help.

Key is to be polite in all interactions. Innocent mistakes happen. Managers are under deadlines too. Paper trial should be maintained regardless of action or inaction.


This is why the financial regulators in the UK have changed to consider the corporate culture when dealing with breaches. A company whose senior staff "live a compliance culture" will be penalised less for the same breach than one operating as described above.

Now you can argue efficacy, being able to pull the wool over the eyes of regulators etc but I think it is a good direction to head in.

All that is way beyond the industry described with institutionalised cheating in tests, it wounds more like the graphics card industry than one with regulators.


Just imagine how Facebook must have (initially) pushed the datr cookie on its engineers: "We only need to track everyone like this to check against DDoS attacks."

Still, even such an excuse should have raised alarm bells, but I assume most developers would just shrug their shoulders and develop the feature anyway, as they would've liked to keep their nice-paying job and juicy stock options.

In reality, Facebook only recently used the DDoS protection excuse for its datr cookie, well after it announced that the cookie would be used for advertising purposes, which also happened a few years after the cookie was introduced.

I imagine whatever Facebook told developers then was even less subtle than "using it for security purposes", and that most of the developers figured it out right then that the datr cookie would be one day used to track users across the web for advertising purposes.


I'm pretty sure people who work for Facebook are completely aware of the company's methodologies and are completely OK with it.

The conversation would be more along the lines of "We need to track people who aren't logged in, suggestions?"


Yeah; in weapons, it might go like this:

* Govt research agency awards contract to study smallpox, including stockpiling smallpox. Researchers are happy, they're protecting the world.

* Govt weapons agency gets notice from govt research agency that "it's ready now."

* Govt weapons agency confiscates smallpox stockpile and data, makes more, spoons it into the tips of missiles.

Original researchers are more or less legitimate victims, whose goal to help humanity was used to obscure the Govt weapon's agency's goal to kill humanity.


Great point, it all depends on how the problem is framed.
