> “That means there’s going to be no steering wheel. There’s going to be no gas pedal. There’s going to be no brake pedal,’’ I'm very skeptical of the claim that self-driving cars that work well enough to be fully autonomous are within reach. How do you get them to respond well to really uncommon but dangerous scenarios? Will they pull over safely when they hear an ambulance? If a police officer is directing traffic at an intersection, will they be able to read the hand signals? Will they know to slow down when a ball rolls across the street? I think the semi-autonomous approach is more promising. The car could automatically take control and pull over if the driver is fishtailing, or drive to the hospital if the driver is incapacitated.

This is why Google is training their cars now in the real world to handle all of these kinds of things. Here's a Ted Talk [0] from 2015 where the head of their self driving unit makes the case for full autonomy vs. semi-autonomous because the semi-autonomous is good enough where people trust it, but not good enough to be trusted. Kind of like what happened where the Tesla driver went underneath the truck that wasn't properly detected.

The scenarios you are describing are incredibly common, and trivial to develop for in comparison to real edge scenarios (not to say they are trivial to develop for). More challenging are things like, "How do you respond to a homeless guy standing on the street directing traffic into an alley", "How do you respond to a flooding on the road resulting in 6" of standing water obscuring all traffic lane markings", "How do you respond to a flooding on the road resulting in 18" of standing water? 24" of standing water?" How do you respond to a road covered in snow (12", 18", 24")? How do you respond to a road covered in snow with tire prints that seem to go into the oncoming lane? How do you respond to a road covered in snow with what appears to be a small 24" high snow drift in your lane? Etc, Etc.. I think the answer to all these questions is, "Initial versions of Automated vehicles will only perform under ideal road scenarios. During Snow, Flooding, or other inclement weather, they will not be dispatched. Wait for future iterations in 2030, 2040, 2050, etc...
