I was talking to Henry at Williams about this today.
It was spun, on the way home from the supplying dealer.
The early arrival of a massive amount of torque catches people out, and once the back end has gone that is it.
As with the NL car, a low mileage on green tyres summer and a cold wet road, plus the arrival of all the torque at low revs played their part.
As much the driver as the car, but for those used to computer managed traction and stability aids the Plus Six will bite..hard.
Winter tyres and possibly a better suspension set up would help, but driver training/awareness are key.
You'd be gutted, wouldn't you..?
Poor bugger..
