My initial reaction is that ride would be painful and handling virtually non-existant. But yeah - cool in a straight line for short distances, moving slowly. Like down to the end of the driveway. Not sure how you'd turn it around to pull back into the garage though.
They probably go like tanks. After all, they are built like tanks, and look like tanks.

Blowing out a tire (tyre) at 65 MPH is never a good thing. Dropping your track and having it jam with no way to steer seems awful scary! Metal doesn't have much grip on asphalt. Might be fun on dirt though!
