New York news radio station 1010 WINS had a story this morning about speeding through EZ-Pass lanes. As a radar detector user, I'm certain that some lanes have a Ka-band radar attached to them. I've occasionally seen troopers pulling people over after the tolls, but it was never clear to me if it was for toll evasion or speeding.
Makes me feel kinda stupid, since for all the flying I do down the highway, I'm that one jerk that actually goes just 15mph through the tolls. Duh.
