Then you’d buy a different car. I’m happy to use the specific gas and roads. I buy it knowing that I’m getting the benefits of that specific gas and road with the trade off that I can’t use whatever gas and roads I want.

Even in this contrived example, you're still allowed to exclusively use your specific gas and roads if the car manufacturer is forbidden from demanding you do so.

Hahahah. Don't get a German car. My god, they would force you to refuel at a fucking dealer if they could. BMW already makes the car go into limp mode if they detect you changed the battery and didn't use an CAN dongle to reset the computer.

Depends on what advantages it gave me. If it was impossible for the car to get into a accident where I hurt myself or others I would certainly consider it.
