It will pole-vault, to an extent. :-) MythBusters set up that exact scenario,
dropping the front of a driveshaft into a pothole with the car at speed, and
the back end of the air caught some air. The car won't flip end-over-end but I
call the rear wheels leaving the ground a pole-vault.

That is part 4, showing the conclusion. The four parts are, in order:

It is also the episode with the 'sploding porta potty. :-)
But the point is, the front of the driveshaft dropping can cause catastrophic
damage and probably injury if it happens at a higher road speed and hits
something in the road just wrong, so the strong loop is a great idea.
