In front of a Waffle House yesterday morning in Houston, this Bimmer had this contraption screwed onto the front license plate. Nothing in the rear. Jammers? Ancient? Sheer curiosity drives me to ask those who might know better than I do.
I remember getting one of these from E-ZPass in NY because I had factory windshield that caused interference.
Surprised they are still around because the modern window transponders don't have the reading issues. In Texas they usually use a sticker version for Toll Tag. Surprised to see this on a Texas registered car.
