A pit start is a manoeuvre used in Formula One (F1) racing. It occurs when a driver pits the car and then rejoins the race lane. The manoeuvre is usually used to improve the driver's position in the race, by taking advantage of the fact that other cars slow down when they enter the pit lane. It involves a driver entering the pit lane at speed, and then quickly accelerating out of it. The manoeuvre requires a driver to have exceptional acceleration and braking skills. It is a risky move and can have a big impact on the outcome of the race.
