They re-wrote the laws to make it like a parking ticket so that they don't have to know who was driving. There are two of them on I-295 I go past every day, morning and night. You can see the car sitting on the sholder (they even have orange traffic cones in front of them so they get the same space each time). Everyone slows down when they come up to them, then resume their normal speed. You have to be pretty unobsurvent not to notice them and get a ticket. They are mainly after tourists/transients, if they catch too many locals they get a lot of bad press over the "they only want money" line.
