Wouldn't the ideal step be to harmonize the radar/lidar technology and have a system enabled that forces a safe driving zone. It's all too common on highways that vehicles can't stop within a safe distance if the vehicle in front of it stops, which leads to 5 vehicle pile ups. You'd only need a moderate percentage of vehicles with the radar/lidar technology to keep a highway reasonably spaced. EG if you're tailgating, your vehicle will brake, if someone is tailgating you it will speed you up (within the speed limit) to get you to a safe distance, or (when capable) shift you safely into a different lane when you're in cruise. Eventually you could simply have vehicles communicate, so when the guy in front of me brakes, my vehicle gets instructed that it's approaching a decelerating object. It'll be small 'safety' steps that will eventually remove human error from vehicle accidents.
