brings up the whole debate (that goes back to the 1980s if not older), “what’s a computer”.
There are people who access the code in those car computer chips. They have a status code when the car is having problems. Some don’t like the notion of HAVING to go to a mechanic to get the reading of that code.
Many of the car companies like the treat the codes as proprietary info. Which is a completely different debate than licensing vs owning software. The smart companies don’t do it though because they know they gain no money with that and lose tons of goodwill.
