We are required to have them in NJ & NY as well. Main reason is so the police LASER gun has a target to hit. Laser does not reflect that well off body paint.
I've done field studies with LIDAR guns, and the front is shit for getting a reading. Grills eat the laser and you can't get a reading. The angled hood is just as bad. It's either bumper (if it's actually flat) or license plate.
