b. Fastest to slowest grouped together, lane selection will be randomly chosen, slower heats race first. (when there are fewer than 12 drivers, the 4 car heats
will be the slower groups)

i. Each driver will be allowed 30 seconds to choose their lane and heat.
2. When there are 13 or more entrants:
