They don’t do it like that where I live anymore. There are transponders you can get to pay for tolls automatically or they send you a bill based on your license plate with overhead traffic cameras and receivers that don’t affect traffic in any way. They’ve been doing this for over a decade, well before modern license plate readers. It’s obviously a little grosser now , knowing how these types of cameras are oppressive, but at this point, I think they’re at the toll booths anyway, so the only thing you’re saving by going for old fashioned toll booths is a dangerous, physically harmful job.
