No, fines are not proportional to wealth (at least in most states). They're either flat fees or pegged to speed. Points on license as well, so ~3 tickets inside a year and you lose your license or have to take a course to keep it.
Most tickets are given by live officers. Cameras do exist, but typically only in dense urban areas. Which opens another can of worms, as police are biased.
We also have lists of secondary offenses the officer can cite only after citing you for speeding (or some other primary offense). Things like a failed light bulb, or some other minor safety issue. These are disproportionately used against PoC.
