I don't know about you but people like machines/robots predominantly because they are efficient and don't make mistakes. Nobody is going to trust a robot car to pickup their kids if you tell them there is a 25% less chance that the car might end up in an accident compared to what it would be if it were to be driven by an average driver. To your point, improving on the average doesn't require driverless cars at all. You ca get that today with just driver assistance technology, improving safety technology on roads, etc - all far easier problems to solve.
