53 of 365 - U is for units of Measure

This is the last day of the transport part of the challenge and the day for "U' in the alphabet challenge, and I am a bit short of ideas! It occurs to me that there are many "U"nits of measurement related to transportation. So this photos has MPHs, Gallons, Temperature, and GPS coordinates all represented. How is that?

I actually took two photos (one of the dashboard and one of out the window) and then merged and manipulated them in Gimp.
