I will have to agree with Becky here, by the end of the feature your mind is wore out from all the racing. You will probably hear people saying "well it doesn't effect me like that" but then if it's not there is still a reserve left and they could push harder than they are.
Mentally by the end of the session I am exhausted and my reactions are not as quick as they were in the beginning during quali so I make more mistakes.
Saying that I feel that in all of LFS this chicane is one of the hardest corners to get fast consistantly, in order to get it fast you have to virtually brush the car on each of the 4 points of the corners to get it as fast as possible, with the addition of the railroad track upsetting the car it's extremely tricky to rotate the car at maximum slip angle safely without running the chance of sliding wide and clipping a few barriers.
Then people would have said "well you should have gone slower" well thats true you could have like in Sam's case. But then your lap times are affected because everyone else is trying to put in as fast of laps as possible pushing you to do the same if you want to be in the top spots. The one thing that the broadcasts are not really showing is the lap times the front drivers were putting in. Regular lap times were in the low 42's throughout the whole night. Making for about 80-90 laps of the most intense racing you will ever have. (Not by any means saying that STCC has the most intense league enviorment, but it's definatly up there)
This is one of the most hazardous corners in LFS IMO and having an accident rate of less than 1% is awesome for a corner that has no room for error, not even an inch if your trying to your fastest lap possible, everything HAS to be spot on, your entry braking, throttle input, steering input, one of these off even a little bit will earn you at least a brush on the wall or a nice drift in the easiest case, all costing you time.
