Dave's using 12 wheel drive !!!

The Moon Buggy that will be in the inaugural parade uses 12 wheel drive. I think we’re sticking with 4.

With the exception of wheels over tank treads, it reminds me of the Chariot from the TV show Lost In Space:

Then again, maybe NASA does take inspration from Science Fiction:
