>humans have been driving with only 2 sensors (eyes) for a long time with relatively good success.

1.25 million die a year in road accidents. We should try to do better than human.

But also keeping speed high enough. You won't have many fatal road accidents with speed limited to 5 km/h. But it won't be very useful transportation. Those timid cars might be safer but people might prefer more aggressive style to reduce travel time.

Sure, but if we can match that number of fatalities with self driving cars it will inarguably be a success from a utilitarian standpoint.
