Well, pretty good until near the end... then he lost the plot! (And I think he might have got a bit of a dressing down by the officials afterwards.)
We run similar events here, motorkhanas, usually in a bit smaller area. The aim is to be the fastest around the course and usually requires a bit (sometimes a lot!) of 'throttle steer' and handbrake turns. Unlike most of the Autocross footage I've seen, in our championship events, we are required to do tests which include reversing sections. Going backwards at a great rate of knots and throwing the front of the car into the finish garage can be quite spectacular - an absolute blast if you pull it off!
My 'stang will be seeing a bit of this type of fun when finished
...and it's definitely not drifting.....
