Traffic

Ever been driving and have some car cut you off, making you think less than decent thoughts about what you'd do to the driver if you could just wrap your hands around their neck?

Well, how about revenge in another way? AIM has the system of "warnings" where you warn questionable/harrassing users until their warning level reaches 100% and then their priviledges are denied. What if we could find a way to implement the warning system to driving?

Imagine... You're driving down the highway and some dope pulls a crazy maneuver. All the cars around warn him using some sort of gadget and instant ticket! That would be so nice. Limits could also be imposed, of course, to prevent jerks from just warning everyone in sight, and to prevent one person from warning another to the point of a ticket.
