Anything happens now in human control. One advantage of automated driving is that nobody would speed and nobody would drive slower than traffic. Vehicles wouldn't have to 2nd guess what the other guy would do so merging into and out of traffic would be smoother. This would also result in fewer traffic jams and less rush-hour traffic.I agree with some of that which is why it got a like, but personally I have more trust in a bus than a self-driving car. Anything could happen because it wouldn't be under your control.
