V1 is the only way to go. I wouldn't cross the street without it! I've got a window mount in each of my cars and I just move it around depending on the car I'm in. Here in Dallas everybody drives 20 over and the cops just love to hide in different places every day.

You still need to speed smart on the freeway. If you don't have some bear bait and blast over a hill you'll eventually get busted.
