So the 13 car companies are now trying to make it illegal for people to modify their cars, based on the noption that people don't actually own their cars. Most people know the risks of messing with their computer system in their vehicles, it can lead to catostrophic failure, in which case any warranty is already voided, releasing the auto companies of any liabilty. But now they are trying to make it punishable by law for altering your car, or doing work on your car period that involves your onboard computer. Now this doesn't only exyend to the owner, it also is supressing shops from doing work on your car who are not certified by the auto maker.
This seems like a huge over-stepping of the rights of car owners.
Edit: Damnit I dun fucked up the title!
