I don't really have any,apart from that the adoption of autonomous vehicles is going to be slower and take longer than people anticipate. Human traffic systems are complicated and not easily modelled, and humans are not easily reassured when events like this happen. While statistically people may be safer with an agent driving, most people don't crash most of the time, so they're more confident when they're in control than when someone else is.
