Hi

I’d bet a warm glass of beer  ( pick up only, no free delivery ) that you will not see them in user level 
modules ( = something you can fire up)  at a rational price ( < $500)  for quite a while ( = years …). 
The target market is integration in self driving / autonomous vehicles. If you are GM or Toyota, 
they will gladly support you. For the rest of us …. go to the back of the line ….. That’s been the pattern
on this stuff like this for quite a while.
