I live in Ohio now, they don't call them the communist highways for nothing. I also have to travel for my company, we have offices in PA, MA, and WI. I drive to all of them. So far I've only ever had one speeding ticket(I'd knock on wood, but they don't make furniture out of that anymore) it was over four years ago, and it cost me $450. I still speed, but mainly just to keep up with traffic.
Oh, hey, it's kinda spendy, but this might work for you.
