He is clearly right about that. Human-driven cars are safety critical and already do fine without redundant brakes and steering. How many crashes are due to brake or steering failure? I'm guessing it's well under 10%.

Most human crashes are due to bad driving, and for computers it will be the same. I mean, even this fatal crash probably could have been prevented with better software. It's not like the brakes failed. They just weren't applied.

This is where he is totally mad.

Human driven cars have redundant brakes. There is one brake assembly for each wheel. The hydraulic system is split into two separate circuits to guard against leaks. Additionally, cars are fitted with an "Emergency brake".
