This is actually a composite of four images (Autostitch).
There was only one car and it was going about 70 miles an hour or better.
Shot while stopped for a break along US 87 between Great Falls and Lewistown, Montana.

Cool! You are having way too much fun with your autostitch software!! I never thought of doing this though. I ought to make a multiple montage of my kids (like 2 of them isn’t enough).
