It's been two years since I thought of asking someone this question but forgot about it and just remembered again today. Two years ago I was on VIR with an instructor in my car. Still learning the track and trying to avoid a late up-shift shortly before needing to hit the brakes, I hit the rev limiter. The instructor yelled "use the rev limiter, it's a technique!" I didn't understand but it was time to hit the brakes anyway so it didn't matter at that moment. Then I got caught up in the fun again and forgot to ask him what he meant. Can anyone explain?
