Sorry to burst your bubbles, guys, but if you're talkng about the M113 APC, there ain't no way it can climb over any car more massive than a F1 racer. It simply doesn't have the vertical clearance.
But back to the APC-on-road scenario, I have a video I simply
must post for you all when I get back Wednesday.

As a matter of legality, here in Israel at least M113 APCs are allowed to drive on roads because of the rubber pads each section of tread has, which prevents the metal from coming into contact with, and subsequently ripping up, the asphalt. Most tanks do not have such rubber pads, and thus aren't allowed on roads.
