why cant a car snowboard ? All it needs is a good set of Michelin tires from the michelin man. As for out the back of a truck, in theory this should work. Just get back tires onto road, they will instantly get up,to speed then front ones. put the car, manual tranny, in 6th gear and dump the clutch. Just make sure you have rollbar, HANS system and helmet on for safety.

Love the commericals that show them flying down a snow coverd road at 60. Only thing they do not show is how to stop quick without smashing the guy in front of you.
