That will take some getting used to.
No matter how congested and seemingly chaotic traffic may be (think Bangkok), there aren't many collisions because the people drive with a pretty good idea what the other fellow is likely to do, and accommodate that in their own driving behavior.
Robots don't have human emotion and don't drive emotionally. They drive safely. Human drivers will have to get used to being in traffic with other cars that drive safely instead of normally.
One can adjust to driving where the rules of the road are a lot different, but there are going to be collisions caused by human drivers who are still trying to learn how to accommodate the robotic vehicle.
Although self driving cars may be safer, it may be more hazardous and annoying to other drivers on the road.
I'm a tractor-trailer driver locally here in Cleveland. About ten years ago my employer purchased a tractor with a VoRad® system on it. It was doppler technology used to supposedly help the operator of the vehicle.
It had a buzzer in the cab that constantly went off on the highway if you got too close (according to the system) to the vehicle in front of you. When using cruise control, it would take over the accelerator of the vehicle. If I got more than 60 feet of the vehicle in front of me, it would quickly slow down. Even if I kept a good safety distance so that didn't happen, it would only be a couple of seconds before somebody switched lanes in front of me and the system would once again react.
It was annoying as all hell to me and the drivers around me. Because once somebody got out of my way, the system would automatically accelerate to the speed I originally set on the cruise control. In short, my vehicle was constantly speeding up and slowing down.
Other truck drivers who were trying to pass me once my truck slowed down would get mad as hell and curse me out over the radio because when the vehicle in front of me left, my truck would speed up and they thought I was Fn with them. It was awful.
Because I had no ability to disable the radar, I finally took some tin foil to work and wrapped it around the radar in front of the truck. My employer was pissed, but I explained that if somebody was following me too close on the highway, and that truck let off the accelerator, I could get rear-ended.
Self driving cars would not only do that, but apply the brake as well once "it" determined you were too close. So you would have a bunch of cars speeding up and breaking quickly on the roads and highways.
