Exhaust noise regulations are generally based on a specific distance and orientation at ground level. How are they going to prove that they met those conditions?
95dB for cars but only 80dB for motorcycles. I doubt my 15 year old bike meets that with its stock exhaust. Regardless, now a car can trip the camera and the blame falls on someone driving a quieter vehicle.
At one point I got a ticket for my car for parking without a permit at a college. The college was in a city that I had never been to, and the make/model of my car did not match the report, so it was obviously a mistake taking down the license. Should be easy to clear up, right?
Apparently no. I didn’t find out about that ticket until I got a renewal notice that was way, way more expensive than normal. I spent the next two months making daily calls to try to get this fixed, unsuccessfully. The advice I got was to take it to court, which would have been about ten hours of round trip driving.
I eventually just paid the ticket so I could renew my registration without incurring a late fee.
I have a very high level of distrust in this system, I hate that another automated crap shoot may be upcoming. I would like the asshole noise machines to stop, but this is not the way.
Automated systems are going to get it wrong, and it’s not worth the risk.
Also, if I had to guess, the reasoning for the limit for cars being higher is that past about 20(?)mph the tire noise makes up for the majority of the noise (which is proportional to weight)
