Italian Red Lights Rigged With Short Yellow Light
suraj.sun writes with an excerpt from Ars Technica which brings to mind the importance of auditable code for hardware used in law enforcement: "It's no secret that red light cameras are often used to generate more ticket revenue for the cities that implement them, but a scam has been uncovered in Italy that has led to one arrest and 108 investigations over traffic systems being rigged to stop sooner for the sole purpose of ticketing more motorists."
I think the problem is that people try to stop more quickly than is prudent in fear of getting nailed by the camera and the result is an increase in rear end collisions from tailgaters behind them or skidding out of control into other cars/objects.
Although, of course, one should not tailgate the car in front of them, they have no control over the car behind them. At times when someone is tailgating me in heavy traffic, I've made a decision to not stop at a yellow light that I could have stopped at. The reason being, I felt that given normal signal timing, if I didn't stop, I would still enter the intersection on the yellow but if I did stop, I would get rear ended. I placed my obligation to avoid an accident higher than the slight risk of a "fast yellow" set to the theoretically shortest possible timing and confident that if a cop happened to be watching, he might nail the guy behind me instead of me (as, the second guy entering on a red is somehow "more guilty" IMHO). If I know there's a red light camera at the intersection, sorry, I assume that the yellow is as short as possible and I stop even if it increases the risk of being rear ended (his insurance company pays for my car repairs, he doesn't pay for the red light ticket). In fact, I had a couple of close calls (guy behind me smoking squealing tires, skidding etc. while I stopped safely behind the limit line without fanfare) at a local intersection that I drive through regularly -- and was annoyed when I read in the paper much later that the cameras had been turned off at that intersection for over a year!
When someone is tailgating you in heavy traffic, you have few options to stopping that behavior quickly - changing lanes isn't always an option, slowing down may just make the problem worse if you're approaching a signal which may turn yellow suddenly since the distance between yourself and the following car - i.e. the margin of safety - is reduced (because the gap is shorter and you're going slower so actually stop more quickly) if the tailgater doesn't take heed of your speed change before you decide to stop for a yellow.
Even with all this care, twice I've been rear ended by a tailgater when I stopped quickly - once for a yellow light, another time for another reason. One of these times, three cars behind me ended up hitting each other also. The car behind me was lighter, more fragile, and had a lower bumper than my car (his was a small Fiat I think) so his impact on my bumper just scuffed the underside of my bumper cover but his bumper, grill, lights, and hood were seriously trashed. (After determining I had no damage I cared about, the officer noted that there was only room for three cars on the standard accident report he had to fill out so, unless I needed the report for my uses, he would just leave me off and I could go on my way -- I always wondered how the guy behind me explained to his insurance company how his car had thousands of dollars of damage and the car he hit didn't even exist on the accident report).
Stopping "as quickly as you can" is just a bad idea unless it's necessary and safe.
Why is there an "insightful" mod and why isn't it "-1"? If I wanted insight, I wouldn't be reading
