I wish we had a POTUS who would fast-track the development of autonomous cars.

26. I disagree. As someone who has worked in electronics all my life

R&D, product development, maintenance and repair I know just how fragile these kind of systems are. No I don't have experience with self-driving vehicles but the sensors, computers, stepper motors and servos necessary are all the same. NASA, the military and many utility companies have systems with auto back up. That means that there are at least 2 complete systems each working simultaneously to do the necessary job when one fails. Because failure will happen.

Aircraft have auto-pilots but they always have pilots. They have ILS (instrument landing systems) but they still require a pilot, and in fact they probably land with VFR (visual flight rules) which means manually.

It was reported in 2014 that there were 253 million cars and trucks on U.S. roads. Consider my 2. I have a 2015 Subaru Forester and a 1994 F-150 pickup that I use for feed, hay and to haul garbage. Both are payed for and to replace them would be prohibitively expensive at today's prices for non-autonomous vehicles. Add the expense of self-driving technology and most people would be priced out.

Perhaps I am wrong but I see great hardship on people who have modest means.
