If you start popping cones and slowing down the event yes people will mind. If you can keep it within reason and and run a respectable time its cool IMO. Cars are sent off the line every 15-25 seconds, if you are drifting and waisting time cars will catch you. If they get to close the car catching you is to be stoped. This results in a rerun waisting time. All you drift guys remember autocross events are a grip event and with 125 entrys waisted time is not excepted. I'm am only a club member not the final say but Shawn or Wes can chime in with the official verdict as they see fit.
