I meant speeding cameras, where a system OCRs your license plate and you receive a fine after a month or even two months. Fine being monetary + points, depending on how fast you drove. Police officers measuring speed have become quite rare, at least here at my location (EU country). While speeding cameras are becoming quite common, especially in towns/cities and on the highways.

TBH, if those became legally invalid, I wouldn't lose a lot of sleep. There's a huge potential for abuse in these things, and their deterrent value is minimal. Especially in a heavily heterogenuos country like the US, where each municipality can have their own rules and their own courts. Sometimes these thing turn into literal highway robbery.
