Boy racer is a term given to a young person who drives in a fast and aggressive manner; it has become a broader term (often pejorative) for participants in modern custom car culture who tune and modify cars with street racing-style aftermarket cosmetic and performance parts such as body kits, audio systems and exhausts.
In the US, "Rice boy" or "Ricer" is a derogatory term for the driver or builder of an imported hot rod, or someone who modifies their car in a cheap way to imitate the look of a higher performance vehicle.
Responses to the boy racer phenomenon range from laws prohibiting certain cosmetic modifications to vehicles such as decorative lighting or tinted windows to restrictions on cruising.
In 2009, a government led by the National Party augmented the Act with the Land Transport (Enforcement Powers) Amendment Act and the Sentencing (Vehicle Confiscation) Amendment Act, which allow police to confiscate and "crush" (correctly, dismantle for saleable parts and destroy the remainder) vehicles on the third offence within four years, issue infringements for "cruising" and prosecute street racing and "antisocial" behaviour, by creating temporary by-laws.
