So that leaves us with two possible reasons the car couldn't have achieved the speed they're claiming. One, it wasn't actually geared to go that fast. Or two, the driver lifted because the car was unstable or he was afraid the tires were gonna explode or something.

It seems unlikely that people capable of building a car like this would have released a claimed speed that their car was incapable of reaching due to gearing. Then again, I've seen a lot of stupid things in my time racing.
