Granted photo radar was a nightmare, but this needs to happen for a number of reasons. We simply can't afford the additional police we would need to solve this problem. The system would need an appeal process in which a violator could view the infraction and file an intent to appeal. Stiff penalties including jail time and or vehicle impoundment  for repeat offenders. More roundabouts would also help but are not practical at many intersections. One cannot argue the additional safety they provide however as traffic is slowed from every direction. Those that advocate "defensive driving" instead of facing this problem need to take a look in the mirror. If your son or daughter were crushed by a speeding F350 your tune would change.
