Anyone see Mythe Busters tonight, they were doing a fuel Consumption
test , A/C on windows up, and A/C off windows down , but the most stupid part was they were worried the tyres would blow out, running around a race track for 7 hours at 55mph, that = 385
miles , what a load of crap,
.

Seemed to be some obvious flaws in the methodology employed by A and J.
1
Test should have been done with the same vehicle to avoid problem of vehicles being in a different state of tune. (but this would not have provided a good TV spectacle)
2 Pumping out tanks did not prove there was no fuel stiill in tanks.
Some vehicles e.g. VW transporters have a fuel tank with
two wells separated by a raised half wall section. Impossible to pump all petrol out if you have put in instead of diesel. You need to cant the whole vehicle over.
Why didn't they just run the vehicle to empty before starting the
test?

Actually they had to revisit this myth later in the series as it generated a lot of Fan (hate) mail....
The revisited result was....
Below about 50mph you are better off with your windows down. Above that speed you are better off with the A/C.
They also pointed out that the exact speed would vary from vehicle to vehicle...

Oh and on the point of the tyres...Back when I was
young..(and stupid) I had a FWD turbo car and Yokohama A008 tyres known for their grip, but not their long life.
On the road under normal conditions they would last 30,000-40,000km's.
On a race track flogging them they would last about 8-10 laps ( 40-50 km) so I can fully understand their tyre concerns.
