To be fair, they probably are safer. Even if they cross into a bike lane, sensor reaction time is far superior to any human. At least a couple of times now I've heard ties squealing behind me in a protected bus/bike line from cunts aggressively changing lane into it to get around traffic and only spotting my bike at the last second. I would feel much safer if 100% of cars on the road with me were controlled by software and not meatware.
