>That way we don't allow individual car manufacturers to make potentially fatal mistakes when cutting corners with their software development.

Wouldn't all the cars by any manufacturer have to pass the same very rigorous driving tests in the first place, to be able to be sold in the market?

Then you will have people writing software with the aim of pass the tests, not real world safety. I don't think auto testing can catch the type of bugs that can arise sporadically, which could be fatal in the case of self driving cars.
