Those aren't their natural voices, these are:
Fuwamoco: Toss-up, if moco is at the wheel then will do fine, if fuwa is then last place.
Shiori: Barely tries
Nerissa: Tries too much, gets fucking salty
Bijou: Asian tryhard unleashed, finishes before everyone else has done 2nd lap.
Hmm, I thought these were their natural voices.
Or are they... preforming...
Anyways BJ is up on the usual site - it's fantastic so you should watch it.
