One for each neuron should do nicely...

I was pretty sure the answer was "slow enough to tail an passenger jet", but I looked up the numbers out of curiosity. Jet airliners fly faster than you might think...according to Wikipedia, the cruising speed of an A320 is Mach 0.78 (which at 37,000 feet is about 515 knots). The stall speed of an F-16 is reported to be somewhere in the vicinity of 150-200 knots, so one could easily keep pace with a cruising A320.

Don't forget the fact that you usually have a limited field of vision in video games as well (at least in my limited experience with driving games), and you can't turn your head to look anywhere other than straight ahead. Either that, or the game puts you in a third person view behind the vehicle, which is better for seeing what's around you but terrible for seeing what's directly in front of you.

I'm wondering how much of an effect Aero Compiz might have had on these results. Aero is enabled by default on Win7 and, as far as I know, some Compiz effects are enabled by default on recent versions of Ubuntu. If power consumption is a real concern, I'd be interested to see this test repeated with both respective features turned off.

Here, you dropped this.

Why not bet on the "yes" side? If you're wrong, you have to pay but hey, you're still alive. If you're right, you're dead but hey, you died a little bit richer.
