agreed, also pick a vehicle that has a smooth slow acceleration. i presume a light truck would be ideal, their slow, lots to grab on to at the back and they wont be swerving all over the road.If you insist on doing it, use a handhold that keeps your wheel a safe distance away from there wheel.
having said this, i don't condone "skitching" neither do i employ the technique myself, but if you are going to hitch a ride, pick the least dangerous means.
