You know how solving 90% of some problem takes 90% of the time, and solving the remaining 10% takes another 90%? I have a feeling that with self-driving cars we are not close to 90% yet, not to mention the last 10%. There is a huge difference between "hey, this prototype kind of works" and polished product ready for consumption.

I'm gonna be honest, I have no idea what you are trying to say here.

All kinds of cool inventions never (yet) got past one-offs. Jetpacks, flying cars, exoskeletons (done in the 60's). If the price, safety, usability, etc. aren't all perfect, it can completely fail. Even electric cars got almost nowhere so far.
