Yeah it leads to real problems for fully driverless cars, as there is no longer a human to blame.
Also note that blaming the human has been Tesla's strategy for avoiding responsibility on their software drive system failures.
Most car - pedestrian crashes in the USA never end up with the driver at fault. Not sure this will change when cars are autonomous.
Well I am talking about all crashes, not just car-pedestrian crashes. For example Teslas crash in to other cars and then the company blames the human driver.
An example used in the paper are the human drivers of Uber self-driving cars - one of which killed a pedestrian in Arizona.
