The problem comes with antenna pattern nulls at higher elevations, particularly on 70cm. I'd be more inclined to look at either a halo-type antenna for each band or a turnstyle, both of which are quite easily homebrewed.
Secondly, yes you can do it, but I'd be concerned about somebody charging down the highway at 100kph+ focusing on a satellite contact, playing with their knobs and not watching for me as a fellow road user.
Yep, I agree, too many distractions alright............ no I mean, stop and work the sat. I will also have a caravan in tow so setting up on a tripod is another option as I can just run coax out the door
