If you have ever been to Indy (5 times) it is more gonads than weight. All the front runners were flat for many laps. Watching drivers go into turn one at 225 and not hearing them lift is unbelievable. You must have respect for every one of them.
I was there when Nigel Mansel raced after winning F1. I had a headset on during his qualifing: he said, I can't F------ believe there's 250,000 people here for quailifing.
In F1 it's one lap. At Indy it's 4 flying laps average.
If you've neve been-Go- You will have amazing respect for the drivers.
