I don't doubt that we have developed the technology to enable a car to successfully go autonomously from A to B avoiding accidents, however driving often involves incredibly subtle decision making...
Will the AI notice the pot hole - and its severity?
Can it tell the difference between a dog/cat/child/deer.
How would it proceed through larger puddles - cautiously? Or without risk.
In a world where all cars are autonomous it becomes easier to manage, in the meantime the technology and its governance must be of the highest quality. I do however commend the US for leading the way.
As well as safety concerns, there are a number of intricacies that will be debated, such as who is liable when a self-driving car crashes - the driver or the software maker?
