Same reason Americans use Phillips head screws instead of something sensible like square drive. Network effects. It may not be ideal but you can get by with it, and most other people are using it as well. Some might look north wistfully, but most around them continue using what they know.
And keep in mind, switching to square drive would be easy. Screwdriver sets already come with square drive bits, and hardware stores sell square drive fasteners. Robertson's patents expired generations ago. If America can't drop Phillips head screws, do you really think there is any chance for replacing the Latin alphabet? Let's get real.
Well, I suppose the printing press has a way of blocking progress. Some languages did manage to update their orthography more recently though, e.g. Lithuanian.
If you look at the former Soviet Union (CIS), you can see a shift away from Russian Cyrillic, so I suppose given enough political incentive, such changes are in fact possible.
I’m going to be pedantic here, but Phillips head screws serve a purpose - they limit torque by allowing the driver to cam out. They’re almost always improperly used, but my point stands :)
Cam-out seems like an ex post facto justification to me. Henry Ford would have picked Robertson if not for the licensing trouble. Robertson's lack of a cam-out 'feature' wasn't the reason.
Agreed, and that's what I meant by "almost always improperly used". Phillips is great for use in plastics in many cases, but they were popular long before that became an issue.
Personally my drive of choice is Torx - they're six-sided so they're easier to align the driver, they have excellent torque transfer, they're hard to "wallow out", and the drivers are relatively inexpensive to manufacture. Beyond that, hex ("Allen") head are good for smaller fasteners where the "wings" on a Torx driver are so small they're fragile, Phillips is good for applications where you don't want it to be easy to over-torque, and plain old "flat head" is very well-suited for dirty environments where grease and debris may end up coating the head. I'd certainly not want Torx heads on the bolts under my Jeep, for instance, because they're a pain to clean out. I can clean out a flat head with the corner of the driver and be able to use it effectively, which is practical unique to that design and very important for those applications.
I have nothing against Robertson. They're as good as anything for 90%+ of applications, it's just that they're uncommon enough where I am that it doesn't make sense to use them.
