Anytime I've done autocrossing it was through a course of cones.
Was this out on a track? It looks more like timed laps than what I have done as autocross.
Which is cool don't get me wrong ... curious though ...
Maybe lack of a track was our issue
I've usually done it in large parking lots or airports for example and you never can get the car going very fast because you have some quick left or right or slalom to go through.
