He pitted infront of me some time later so I stayed out for one more and came out way ahead, not sure why. ...
From the car.ini for each car
TYRE_CHANGE_TIME_SEC=10 ; time spent to change each tyre
TYRE_CHANGE_TIME_SEC=20 ; time spent to change each tyre
That's why. And I might change cars.
Apart from that a ding dong race, took Bruce out early by out braking myself, took Joe out as described above but mostly took myself out on the second lap whilst leading.
But none of it spoilt my race, except that I didn't feel the Alfa gave me any advantage especially down the straights, only thing going for it is that 4WD lets me avoid a lot of spins as you just keep your boot into it and let the front wheels drag you out.
