The pressure is not high enough and the hole is too small. Explosive decompression only occurred when a hole the size of a window was made with explosives. Even then, the rush of air could not suck Buster completely out of the hole. Lastly, there are proven instances of explosive decompression where the plane was still able to maintain control and land.
(This myth was revisited in episode 38 and it was re-busted.)
The bullet did work as a replacement fuse, however when a short circuit was created, the wiring fried and the bullet did not fire. When the wiring was upgraded to a higher gauge, the bullet did fire out of the fusebox, but not with enough velocity to cause any serious injury.
*Though both Adam and Jamie admitted that the myth was plausible from their tests, they had to call it busted due to a lack of conclusive evidence, and the fact that they didn’t have a "plausible" verdict during the first season.
The rear axle was able to be pulled loose, but only after several bolts securing it were removed. Additionally the axle was caught along the underside of the police car and could not clear the trunk. Adam and Jamie theorized that, in the movie, a ramp was used to give the car and axle enough of a boost to wrench the axle completely free.
