> I put the self-driving car in the same category as the flying car and jet pack. This one just happens to have VC funding. Flying cars and jet packs are limited by physics (specifically energy density) and progress in this area is almost non-existent. We barely got batteries to be vaguely competitive with internal combustion. Self-driving cars are limited by software and hardware accelerators and this field is making real progress.
