We'll be doing back to back runs, similar to the most recent motorkhana, which seems to move through the list of cars pretty quickly.
This means more runs per car for the entire day. Definitely won't be having a full line of cars queued at once, we'll most likely be calling groups of 10 at a time.
HH is a good spectator track, so sitting in a queued car all day isn't the best outcome for anyone.
