I don't know if this counts as a tin foil hat conspiracy theory but I believe it
I believe that a certain percentage of speed camera tickets are BS
You don't get the ticket in the mail for 3 or 4 weeks (or longer), there is a picture of your car and the your listed speed is plausible not outrageous
You know damn well you weren't going 80 MPH in a 40, but 52 mph? That's possible
I once got a ticket saying I was going over 60 in Washington DC at like 8:30am. It's not even possible to go that fast on that street at that time of day
Basically, I was told "tough shirt, that's what the camera says, that's the price you have to pay"
In the same vein, when red light cameras first became a thing I know for a fact that the duration of yellow at some lights were shortened
