With regard to ticketing for gridlock, I wish the authorities all the best on that one. I see a lot of drivers doing a lot of stupid stuff in that regard. A few more tickets might be helpful for that.
For other stuff, not so much.
About a month ago, I got a letter in the mail from one of the toll road places. They said basically "Pay up, we got a picture of your car going through one of our toll booths."
Since I haven't owned that car for years, and it was an old license plate number for it even then, I called them.
The nice lady on the phone (and she WAS polite) pulled up the photo. Then she told me it was an Oklahoma plate, not a Texas plate. She said essentially "No problem, I'll fix it for you." I made sure I wrote down her name and the date and time of the phone call, just in case.
A bunch of years ago, NYC traffic cops weren't "real" cops. They were traffic cops, usually referred to as "brownies" for their uniforms.
They always wore long raincoats.
Always. All year long, and in all weather conditions, including heat waves, etc.
See, they would pull stuff like wave a car into the grid, and then that same Brownie would ticket that same driver for BEING in the grid. If the driver tried to fight the ticket by saying the traffic cop waved him/her into the grid and that, by law, a cop's traffic instructions to a driver overrides any existing lights, traffic signs, and quite a few traffic rules (emergency detours taking a turn that usually osn't allowed, etc.), the judge would point out that the Brownie wasn't a real cop, so had no authority to do that, and the driver should have known better...
So people started opening their windows as they passed Brownies, and would yell things, throw things, and spit on them.
Raincoats.
They've since been absorbed into the regular force and union, so I wouldn't suggest spitting or throwing anything at them now.
I believe theoretically speaking, a member of the public can report someone for breaking a traffic law. However that's rare, and might come down to one word against the other. I guess by extension, a police officer could so the same, but extremely unlikely, as an officer would usually pull the person over there and then or forget about it.
It can come down to one person's word against another, but then the question becomes one of who has something to gain by lying.
I've issued "Improperly Passing School Vehicle" a couple of times. My son is disabled, would take a properly-licensed and identified minivan that was a school vehicle to transport students to school. (He will again, once people at his school stop testing positive for CV19.)
My "neighbors" didn't like the idea they were supposed to stop when the can had its red hazards on, and would squeeeeeeeze past it as fast as they could on a single-lane street, leaning on the horn because... entitled. Meanwhile, they put the kids, who don't always respond well to being startled, as well as the driver and aide at risk of injury.
My word against the jerk, right? But what did I have to gain by lying? A safer street? What did the driver have to gain? Dodging a fine, possible community service, possible jail time, 5 points on the license that would result in state surcharges of $1000 for 2 years, and insurance premiums doubled for 3.
The catch is I had to go to court, which I did.
