My car will probably go (at its best) about 300m on a tablespoon of fuel. About a fifth of a mile. But it weighs about 20 times as much as I do, so I think that's pretty good going. With a rolling start and flat ground it will pass this test at 30mph, and probably higher too. That's quite a lot faster than I can run, too...
