Her choice of vehicles is just that she likes big trucks, always has.

I think she has a lead foot in the city but from our house to the highway(where the speed limit is 65) is about 2 miles and when she gets off the highway it's a little over a mile to her work. She says she drives 65-70 but since I don't ride with her I can't say if she actually does. She's starts work at 6am so she doesn't deal with rush hour traffic either.

Thanks for the response, it does help some.
