Supplementing unreliable warning systems - they will be unreliable given that you'd have to wait for older cars to be cycled out of service - for good driving habits seems like an obvious recipe for disaster. Even among good drivers, I doubt many people really want another device competing for their attention when they're trying to make a decision. # So, I suspect somewhat more sinister motives. It would be a lot simpler for law enforcement if they could just stick up small stations to monitor everyone within an area, rather than having to put speed cameras and so on there, and it would allow other behaviours than speed to be automatically analysed.
