Sorry, but I really believe the only ones really opposing them are those that have been or fear being caught and fined by ignoring the requirement to stop at a light. The same as many cyclists ignore stop signes and red lights while riding, that just carries over to the car. If one gets used to following the laws, how those that are caught that don't becomes a dull and boring point.

I like the analogy and complete turn around of some peoples thoughts on use of photographic evidence when it was used for the slightly different purpose of prooving guilt on creating a paraplegic. In that case, it goes directly to criminal as it's often vehicular assult that drivers hitting cyclists and pedestrians are charged with.

Bring 'em on, and put them on bike trails as well so they can take pictures of the cyclists faces. As an experiment while in Germany several years back, after a few cycle / pedestrian accidents at an intersection, they had a sensor camera with a cop sitting a few hundred yards later pulling people over issuing citations. Had a radical impact on how many cyclists ran the lights and stop signs on that trail.

While it may change the habits of riders and drivers, it's not always a bad thing
