That begs the question, would a jet powered car go off the front of a treadmill that could move at an infinite speed?

Of course, just like the plane would move. This is simple physics. There is no force that cancels out the force from the jet.

This is essentially the same as asking if a jet will cause motion over a frictionless surface. The answer is yes, because the jet is not relying on transferring power to the ground to move.
