The biggest difference in the wet between F2 and F1 is that there's so much more power in F1 as being on the throttle earlier has a bigger advantage.
I think what I've found is that in IndyCar, the balance is a bit more all over the place compared with Formula 1! You have to get used to that and work around it. Again, as a driver, you can help the situation by the way you brake and apply the throttle to make the balance better.
When it's wet, you're much more tense on the steering wheel, you have to dance with the throttle and the brakes more. Each lap is a different scenario, so you're really on the edge of your nerves. One mistake could cost you the entire race.
In Formula 1 there is so much grip, you can attack the corner so hard and be so aggressive in corner entries, and that doesn't really work in IndyCar. You have to bring that back a bit and be more precise in the mid-corner to exit.
Those who have come into Formula One without experiencing cars devoid of electronic aids will find it tough. To control 800 horse power relying just on arm muscles and foot sensitivity can turn out to be a dangerous exercise.
Despite the name, 'lift and coast' does not mean cruising. You're trying to be as fast as you can, and you're still going through the corner on the limit, but you have to approach the corner slightly differently; otherwise, you won't make the end of the race.
There are times I'm approaching turns with my right hand on the brake lever, I'm downshifting with my fingers, I'm controlling the throttle with my left hand and steering into the corner with only one hand on the wheel. I feel a bit like Jimi Hendrix: I play with both my hands.
The Harley's got a little too much torque when it comes to jumping.
Stop-Go seemed more sensiblr than using the brake and accelerator at the same time - a practice that later became fashionable.
There's so much more power, so you're short-shifting all the way down into fifth, sixth, seventh before you can get the full throttle. But great fun otherwise.
The throttles could only move very, very slowly, always watching the temperature, always watching. And even in throttling back, you could bust it, even being very careful.
