This is true, Kim, but one should normally never have to begin braking before the finish line in order to avoid a DNF in the runoff zone after it.

I don't think anyone here, myself included, has said that this was an outright safety issue, although it never hurts to look at every aspect of the course design in terms of the "unforeseeable" (total brake failure, stuck throttle, a driver having a seizure or heart attack, etc.) happening. I am trying to make a general design suggestion, based on principles of AX course design I have seen practiced for years in our club and others, namely to include slower segments at the start and finish to maximize safety, conserve wear and tear on equipment (clutches, transmissions, tires, brakes, and timing lights) and to minimize cone carnage, which can cause delays in the event while the course is reset/rebuilt. There is also a "fairness" element to these suggestions, as higher HP/weight ratio cars benefit from a "dragstrip" start, and less skilled drivers in later cars with ABS can certainly benefit from the kind of shutdown that was required after the finish at the last two events.

Thanks all for the complements, comments, concerns, and critiques. After re-reading and seriously considering it all I do see that they come out of hearts to help us all get better at this, and a desire for safety.

Tom, I had no idea that there were any issues last month with finish this is the first I have heard of it. I am very sorry that you were placed in that situation and glad you guided your student safely through it. I will strive to continue making courses that challenge us all, and maintain a high degree of safety. I try to keep all of us out of 1st gear after start, but if you see a series of tight S turns next month, it may be just to get people slowed for finish. 8) My initial plan was to run nearly the same course but in reverse, but with the parking lot exploding under us I am not sure its a possibility.

Actually this all brings up another conversation, one of shared responsibility in autocross, but I havent fleshed it out and will post it in another thread if I do.


Thanks again for all your thoughts.

I never felt that there was any threat to anyone's safety or I would have made him stop and I would have gotten out of the car. He did, however, DNF after the finish in the same way many people did yesterday, going off straight between two cones, and also hit some cones going wide in making the turn to grid when he got a good run at the finish line and had trouble slowing down in time, so I had to advise him to begin lifting before the finish and start braking earlier, which is something I have never done with a student before. He had quite an unusual car, so some of this is a consequence of the new policy of allowing X class entries by non-members. His only prior performance driving experience was drag racing, so he could get the car going very quickly in a straight line.

I see the emoticon after your sentence, Mark, but just to be absolutely clear, I will say without equivocation that any turn on an AX course that requires first-gear after the start is beyond "kinky" and lands squarely in "constipated" territory. :lol:

You guys are the best. As the father of your newest Driving Instructor, Michael Ma, I have to give credit to Adam Gill, Sean Malloy, Joel Bowman and Jackie Corwin for encouragement and mentor-ship. I believe you all practice the PCA motto, "It's not just the cars, it's the people." I am really enjoying the fun, competition and camaraderie in the club. Father/son bonding is an added bonus. However, the first order of business in our household is to have Michael as my instructor, I'm tired of him beating my butt every AX in MY car! :D
