"If."

So far, every self-driving accident where the self-driving car was found to be at fault follows the same pattern: the car had all the sensory data it needed to make the right call, and it didn't make the right call. The bottleneck isn't in sensors.

In that case we're probably even further from self-driving cars than I'd have guessed. Adding more sensors is a lot cheaper than putting a sufficient amount of compute in a car.
