thats the problem with any kind of ratings system like that - it can get mob-abused....
still if we had some way of making a totally democratic one - your car detects tags on surrounding motors and puts a small up/down increment on a central logging server depending on how you respond, it would water out that sort of behaviour.... you'd soon get to see who's causing the most disruption or being the nicest by their accumulated marks
you could have some kind of regional award at the end of the year where the 5 nicest people get a new car and the 5 biggest idiots have their license revoked and cars crushed
i take car-body language action to try and remove some of the puff from their sails these days. no-one wants a crash so it ends up a little like chicken, maybe dangerous, but if you can freak them it might make them think twice in future... dont dive out of the way, just calmly shift aside just enough and just in time to avoid an accident.
also i have a habit of dodging those flying up behind and not changing lane early enough on the mway.... either onto hard shoulder or middle lane, and brake so they go by faster and often have no choice but to continue passing if they're close/fast enough... (once, onto the other side of the road on a single carriageway)
