Dunno what it is exactly.
A lot of car shows have different "events". Local one has a "go to whoa", starting and stopping on lines 100m apart and timed. Then there's burnouts.
Other ones have a cloverleaf motorkhana, with a drive in bay, reverse into next, drive into next, reverse across line. Spear a spud (passenger has to spear a potato in a tyre at each of the bays).
Looks like some combo of a lot of the general ideas.
