I once tried to squeeze into a mock up of a F1 cockpit, at a car museum, and it was not a pretty sight. I had to turn hips up some. I could neither straighten my legs nor lean back all the way. The awkward position meant that my boyfriend had to help me get out of it as our girlfriend stood by laughing and holding our son back from trying to get in with me.

Obviously those guys aren't 6'8" tall and weigh less than 265 pounds.

My son fit in nicely and probably will for a few more years (21 months, 36" tall, 33 lbs.). I don't see F1 driving in his future.
