You can't stop all this, but I am covinced we can keep these bastards from going thru red lights. I mean say 5 seconds or so after it turns red(so nobody can say it was yellow-thought I could make it...Mlissa fkn Manchester style,) they could have an ubstruction of some sort go up(that, or activate underground magnets progressively.....so the car gradually is slowed before it can go into the intersection.) If we can go the moon, we can sure keep trash from going thru a red light n' taking the top off cars.
