With cars I want to underscore what I said about a "10X" improvement in safety and convenience. That is not just polishing a turd. What does it take to actually get to a car that largely drives itself, on myriad roads and conditions? It is wishful thinking to believe cars will do this all by themselves without drivers anytime soon.
Instead, think of a UI that is much more about "mind-melding" with a human driver. Letting them know exactly what it is planning to do, how it intends on navigating that stretch of Highway 1 without driving off the cliff. THAT will probably require fundamentally rethinking the cockpit. You will be mostly focused on "driving by instruments".
If they can achieve that, then we get cars that really do save thousands of lives and make the journey much more relaxing.
