I've always done better with filming it. After that, I take screenshots of the footage to get my individual photos. I'll admit that it's pretty tedious work, though. Hopefully someone else comes by with a better idea for you to try.
If you want to snap a picture while the vehicle is moving, then you will need a camera that has a decent autofocus feature. What kind of pictures will you be taking, though? Blurry ones would be acceptable for motion pictures.
