Here's how to do self driving cars in a reliable way. First, instead of cameras that try to use road markings designed for human eyes, use specially designed roads with guide rails on them to ensure it follows a safe path. Second, for added convenience, these roads could also power the cars so you don't need to stop to charge. Then we could even connect those cars together to increase efficiency. To mitigate the cost, no individual has to own them, they can stop at fixed points to pick up and drop off passengers, charging an affordable rate for each trip, or monthly/annual passes for frequent users. Maybe we could call them trains.
