... otherwise someone could easily steal your design, write up a patent for it, and beat you to the patent office. Now you're out of business unless you pay royalties to them because they beat you to the office first.
Makes me wonder what FOSS software hasn't been patented yet, seems like all you need to do now is file a patent and you can claim ownership over a project that you had nothing to do with.
+1 - as someone who HAS driven a formula race car before (even one not remotely as fast as an F1 car, but still immensely quicker than any street car), I can confirm that it is VERY physically demanding. You wouldn't believe the amount of effort it takes just to keep your head upright. I'm a fairly decent athlete (although not pro caliber), yet before doing a concentrated workout routine, I couldn't go more than about 5 laps before I was just too physically tired to continue safely.
It's a fairly minor workout for your legs (although remember that the brake pedal of an F1 car takes nearly 100# of force to push down, ~15 times a lap for 50 laps), but it is a VERY intense workout for your arms and neck.
Anyone who doubts this - I challenge them to just 5 minutes in a 125cc go kart. Despite having nowhere near the capabilities of an F1 car, you'll still get a sense of the physical exhaustion involved. If you can go 20 minutes (at speed) without special training, I commend you.
