I have been struggling with trying to snap pictures while in the car. I'm not the driver, so no worries. My pictures look blurry because we are moving.
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.
