You are only concentrating on the motor control. I am not sure about the
technical skill of the American automotive industry (grin, grin), but at
least in Europe SOME cars already have some safety functions based on
computer systems for good reason.

Right. The car owner must. But what happens if he doesn't? After a major
accident, will the lawyers really sue the car owner? Or the company who
let the car owner tinker around in the ECU?

Keep in mind that for most car owners, it is much easier to understand
the safety aspects of a mechanical modification of the car than all
safety aspects of a SW modification.

Just out of curiousity: Which percentage of that SW is already GPLv3?
