Once upon a time, in a world without computers, the internet, and autonomous cars, a car was just a car. It was a bunch of moving parts that all fit together perfectly and, if something went wrong, then a gearhead could mess around with those parts and set things right. That was then, but this is now and automakers think you’re going mess things up but good on today’s complex cars. They’d like you to stop and are seeking protection under copyright laws, but at least one U.S. Senator thinks this is a bad idea.
