I have paid a couple of these in Washington DC, and really do not recall that I was going that fast, but going to Dc to fight a losing battle against people who only want my money isn’t in my plan. My plan is to go around DC and not through it any more. It’s a money making scam, that’s for sure.
to hell with paying for all those expensive gadgets. I don’t have a front license plate and my rear plate is obstructed on my work truck. Highway patrol has yet to pull me over for it (knock on wood).

Whe were able to drive on the toll roads in one state with impunity without paying the tolls because we had out of state plates and were moving to another state. When we got to our new home we licensed our car in that state. It will be interesting to see if technology has caught up with that sort of license movement yet. It was a sort of test.
