Indeed. Eventually it won't even be fine print. They will all do it, and you will have the choice of renting a car or not.

It's not even a question of there being a conspiracy, it's just a combination of incompetence and apathy. As an example of how easy your scenario is to achieve I received a letter from the courier division of the Norwegian postal service last Saturday. It asked me to complete a form and the form was this:

[ ] I agree to pay a fee (subject to change) and to pay the import tax on the package and on every other package ever.

[ ] Send my package back to the UK and I'll never receive anything ever again unless I agree to choice one the next time.

So, pay the fee and agree to the T&C or GTFO. Having already paid for the item and it keeping my car off the road I was left with no choice but to cough up the (extortion) fee.

This would still be problematic. What about the people that get into the car with you? They haven't agreed to anything.

Additional fine print. It is your responsibility for informing your guests that there is an active camera in the car.

Does it need to be a fine print? (why not something that's easy to see?) Here in New Zealand, some of our taxis have cameras. So even before entering the vehicle, it has "Under surveillance" or whatever on the windows, and additional stickers inside the car.

On that note though, I wonder if their cars will be much cheaper to rent than their competition to make consumers feel better about it.
