I agree with Addertooth, but it is tricky to "see" grip.I really need to work on remembering the course in more detail during the course walk, I think that'll help a ton.
I was thinking the same thing...the op isn't bad at driving cone to cone, but there are some spots when more speed could be carried by looking a bit further.Your doing great, if this is only your second autocross your getting very fast very quickly, nice. The other thing I would add to this previous comments is look ahead 2 - 3 - 4 gates. Although it is hard to tell from the video you appear to be looking at the next gate only and not far enough ahead. If you watch the top autocrossers they are often looking out the side of the car, several turns ahead.
