Let's think about where technology could take this.
First you get a black box that can be read after you are pulled over by a police officer.
The next logical step is to have the black box wireless broadcast information about your car, speed, etc. as you are driving that can be picked up by police officers along the side of the road.
The step after that is a smart highway that checks up on you and sends you a traffic violation to you via text message, email and instantly deducts the fine from your bank account without the need for human intervention.
