This kind of shit is a waste of taxpayer money. I don't agree with automated ticketing. However, if it is clear that the vehicle was speeding, and it is clear that it is your vehicle, and there is no stolen vehicle reported... give me a fucking break.
Maybe it wasn't actually you. But you know who you gave your car to that day. You know who was speeding in your car. Either get them to cough up the cash to you, or deal with the fucking fact that you trusted someone else with your car - clearly, someone who doesn't deserve to be trusted.
I hate cops. I hate stupid laws. But more than that, I hate people who look for loopholes to absolve themselves of personal responsibility. Don't fucking loan out your car if you're this type of asshole.
