I don't see how this is going to be very different to today. All cars must meet a minimum standard defined by the regulations, such as crash safety, lighting, performance (the UK MOT test checks this) etc. And if you pay more, you get more: better brakes, better lights, more airbags and so on.
If cars become more like PCs, then I just hope it doesn't mean my car will need continual hardware updates and memory increases to carry on working whenever I install a now OS, I mean, whenever I drive along a new road.
