The only cops who have any prayer of answering technical questions are working in 1 Police Plaza and only put on their uniforms for parades. Most of them still have VCRs flashing "12:00:00". And yes, VCRs!!! I'm trying to figure out how we can get our bikes to levitate not to trigger a sensor. There are sensors at roadway level but they're only used to figure out the size and number of wheels of larger vehicles. The most important thing with the E-Z Pass is to make sure the radio signal path is not blocked and that the tag is aimed in a useful fashion. Deviation will reduce performance and may result in failure.
