What i find laughable is that they stubbornly refuse to test braking distances at higher tire pressures. It would be a really easy test to do for them. Instead i see then going to great lengths to prove/disprove this and that. Yeah the explosions are cool and so are a good few of their experiments. But i still don't see any mythbusters tire pressure testing.
As for dirty vs clean......hardly measurable i'd say. There might be some difference found if they do the exact same test over and over all day long and get a good average. But i bet it'll be tiny, if any at all. Grumble....grumble...moan......
