A giant hairpin is a place of most excitement at a karting race, although karting is different from Formula 1 in that passing can happen all over the track.

Three 250cc two-stroke karts driven by members of the public battle in the hairpin at the Circuit Carole outside Paris at the Kart Discovery fair in February.
