In my opinion, every manufacturer of a programmable device should not be allowed to prevent the buyer from reprogramming it.

You're legally (and technically) prohibited from re-programming GPS modules, GSM modules, and probably many stuff in cars as well.
(Actually, maybe contractually when it comes to GPS modules.)
GPS et al would be non-functional if everybody could make a jammer.
(That’s not to say that app stores fall even remotely in that category.)
>GPS et al would be non-functional if everybody could make a jammer.
Then it should be illegal to make a GPS jammer. Making it illegal to reprogram a GPS receiver in any way is unnecessarily broad.
It would be difficult to catch in an inspection if you could reprogram the OEM parts.
I don't care about closed-course cars, though. Do whatever you want to your track/drag car, but cars on the highway should probably have stock software for functional parts.
Essentially all passenger cars use physical/hydraulic connections for the steering and brakes. The computer can activate the brakes, not disable the pedal from working.
But also, this argument is absurd. What if someone could reprogram your computer to make the brakes not work? They could also cut the brake lines or run you off the road. Which is why attempted murder is illegal and you don't need "programming a computer" to be illegal.

People already do this. There are also schmucks who make things like straight-through "catalytic converters" that internally bypass the catalyst for the main exhaust flow to improve performance while putting a mini-catalyst right in front of the oxygen sensor to fool the computer. You'd basically have to remove the catalytic converter and inspect the inside of it to catch them, or test the car on a dyno using an external exhaust probe, which are the same things that would catch someone reprogramming the computer.
In practice those people often don't get caught and the better solution is to go after the people selling those things rather than the people buying them anyway.
