Says who? To be a "car", it has to have wheels, not necessarily tires. Tires would disintegrate at such high speeds.

I've always thought that the key to going fast underwater was to project some sort of gas in front of the craft so there is less friction and resistance from the water. I haven't seen anyone actually do anything with my theory though, since it's been a casual and informal one - but it's mine, nonetheless 
Instead of thinking that the body work needs to withstand 12 tonnes / square meter, maybe we should be looking at how to make the pressure on the body work be less.

Power to drag will dominate everything. This is really an exercise in aerodynamics. Cutting the surface pressure would certainly be good, but the big payoff would come if they could reduce aerodynamic drag, regardless of peak and nominal pressure levels.

This is cool, but I have one question- aren't 2 runs required in order to get an official land speed record?
If yes, then is the rocket going to only consume half of its fuel per run, or will they have to refuel it?

What the F. I've never done research in this area or anything so i'm quite certain I didn't get the idea from somewhere else, because the term sounds completely unfamiliar. But who knows!
