is currently seen as the cheapest and easiest way to race bangers and harks back to the sport's roots of simple preparation and large grid sizes. A banger race is distinct from a demolition derby, as the objective of the latter is not to turn laps, but to smash, destroy and ultimately immobilise all of the opposition, until only one vehicle is left. On occasions, though, the final event at a 'National' or 'Back to basic' Banger meeting may be a demolition derby where the cars that have raced compete to be the last one standing. At special events, caravans or small boats may be towed by racers during the demolition derby for added destruction during the event. At regular banger events, cars are gridded across the track, sometimes in a graded order of driver success, and then sent away to give a rolling start for the beginning of a race. Despite the racing element of the sport, the community often categorise drivers into two different groups. There are those who are regarded as 'rodders', a term derived from the Hot Rod formulas that also commonly race on short ovals. These drivers aim to win races by any means possible. There are also those who are known as 'wreckers' and compete with the intention of destroying their own and other racer's cars. Wreckers are often more popular with the crowd, although drivers who win races and qualify for the world final are also respected. Along with trophies for race winners and podium finishers, there are often trophies presented to the 'Best wrecker', 'Best entertainer' and 'Demolition derby winner', in order to attract drivers of both persuasions. Another trophy often given is a 'best car' award which is usually either given to the best-presented vehicle or the rarest car; with the latter being the subject of much controversy with classic car enthusiasts. In a banger race, yellow flags are used during the race to warn drivers that caution is required. Cars which stall or are stopped by opposing drivers are usually left on the course while the race continues. In recent times, drivers have been encouraged to remain inside a disabled car while the race continues, as this is adjudged to be the safest option. The largest association of European promoters has indeed mandated this, it is now a punishable offence to leave a car during 'green flags' unless deemed an
