If you want to be f1 driver then what qualification you will need to participate in f1 race ?

How fast would a formula one car need to go to drive upside down for a period of time and could it actually be done?

Is there a tool used in formula 1 pitstops which allows the wheels to align properly like the machines in large garages? It seems that tyre wear would be reduced by a large amount if something like this was used.

I heard that a Formula 1 car travelling at 200 kilometres per hour would generate enough downforce (or suction) to allow it to stick to the ceiling.

Is this correct? And if it is, how is the force generated?

This is an interesting thought-experiment and gave us some great answers. Clearly the long-running debate over how aircraft wings achieve lift is still alive and kicking - Ed

A single Formula 1 car passing by makes a noise of around 110 decibels.

Last year I went to a Formula 1 Grand Prix and sat near the start line, where 20 cars left the grid at once.

The noise was mind-numbing, much louder than a single car, but not 20 times louder (or 2200 decibels, an unachievable figure). Why wasn't it?
