For example, I've been recently pondering how to resolve tailgating. How about a system like this: Vehicles will be mandated to have distance sensors in both front and rear (some already have this for sake of back-up cameras and auto-braking), essentially a car sonar system. If your car is moving, it detects the distance between you and those in front and in back. If you are traveling too closely to the car in front of you (tailgating), your vehicle will be mandated to emit a warning buzz sound in the cabin, which intensifies in strength the smaller the gap. For someone tailgating you, perhaps a visual indication behind. This way the closer one tailgates, the more audible (and possibly visual) feedback a driver gets. Hopefully the audio is annoying enough that most sensible tailgaters (oxymoron?) would back off. Strengthen this with a visual indicator on the roof of the vehicle, perhaps, so that if someone is tailgating, a light on the roof turns on indicating such. Would make it trivial for police officers and traffic cams to notice. I think part of bad driving behavior is the anonymity cars today offer: with tinted glass and the feeling like you're in a safe, sound-proof cocoon, so this visual indicator may help shatter that in a good way.
