1 - about 2 minutes after the rain stopped the back of the car stepped out on me in the porsche curves and i swiped the barrier. The muffled voice in my ear told me i had a puncture - the result of the crash or the cause of it? I`m not aware that i made a mistake there and i doubt my soft wets would have degraded that quickly.
Yes as Busi said punctures only occur and wheels only fall off from an impact (I think the pit crew tell you you have a puncture when the wheel has actually come off). A few of the corners on the track (that one included) can catch you out. I almost lost it there my self at one point when Jon was in my mirrors.
2 - on the drying track i was having problems braking, especially at mulsanne corner - i just seemed to run out of braking effort - was that down to wear and tear on the brakes or standing water?
Again, I agree with Busi. Its all about using the audio as a queue to wheel locking and its harder to pick up on in the wet as the noise is different than it is in the dry, more quiet. As you get down to 2nd and 1st gears when braking you would have needed to back off the brake a little to reduce locking.
3 - is it possible to drive a wrecked and wheel-less car out of the gravel trap?
As long as you have at least 1 wheel on the back of the car its theoretically possible but, the car can get really wedged in the gravel some times. If you have that game set to use a manual clutch you would have needed to use that as well.
Well done H@L, you alien!
Maybe on this track but, I have done a crazy amount of laps here with variable weather and I still was not close to the insane qualy record of low 1.43.
