Interestingly is there a potential moral issue in the making here? What happens if/when self driving dependency is so prevalent that the majority of inhabitants in a city don't know how to drive. In addition add the fact that self driving cars don't have a steering wheel so even people who know how to take over driving can't actually take over.
What happens if there's an event that requires a mass evacuation such as a Category 5 hurricane and the major self driving car companies deem it too risky to drive in the conditions that precede the storm?
