Here is my proposal for self driving cars: forget trying to make them drive on local roads at first. Add transponders to all interstate tarmac that can be used to detect location and lane position. Then use a much cheaper LIDAR just to map where the other cars are. Boom: you have made long haul driving autonomous. You can then slowly expand this to smaller roads. But why try to recreate human drivers when machines can use much better sensors than us, but can process visual info much slower, and gather it with worse fidelity?
