The regulations governing Formula One racing have changed many times throughout the history of the sport. Formula One's rules and regulations are set by the sport's governing body, the FIA.〔(【引用サイトリンク】title=About FIA )〕 The primary reasons behind rule changes have traditionally been to do with safety. As each decade has passed the FIA have made more and more changes in the regulations so that better facilities and equipment are available in the event of an accident at race meetings.〔(【引用サイトリンク】title=General )〕 These rule changes have also been aimed at eliminating dangerous practices from the sport in an effort to make it safer.〔 Many innovations and technological improvements have been banned over the years as a result of FIA regulation changes. The governing body have taken these actions to slow the cars down to a level where a Grand Prix car can be driven relatively safely. Without this pruning of the sport's technological advancement cars today could be capable of cornering speeds in excess of 300 km/h. The result of an accident at this speed whilst negotiating a bend in the track would almost certainly be the death of the driver.〔 Since 2000, the FIA has been issuing an increasing number of rule changes to limit the cost of the sport. The cost of running a team in the sport has increased dramatically in recent years and this situation has not proved sustainable. From 2009 onwards, Formula One has committed itself to dramatic reductions in expenditure. == 1950s: No thought given to safety == Although Formula One races had been taking place since 1948, it was not until 1950 that the World Championship was established. Safety was almost a non-issue〔(【引用サイトリンク】title=Newspaper Analysis: The Times newspaper reporting of fatalities 1950–97 ) 〕 in the first 10 years of racing and technological progress was extremely slow compared to modern standards. All of the circuits that Formula One raced on in the 1950s had no safety features; the general mentality was that death was an acceptable risk for winning races, and as a result very few regulations were changed during this period. ; 1950–1953 : Engine specs set at 1500 cc maximum size for engines with a compressor (supercharger or turbocharger) or 4500 cc for normally aspirated engines. No weight limit.〔(【引用サイトリンク】title=Formula One era: 1950–1959 )〕 Note that in 1952 and 1953, the World Drivers' Championship was run to Formula Two regulations (maximum capacity of 750 cc for engines with a compressor or 2000 cc for normally aspirated engines), but the Formula One regulations remained unchanged, and numerous non-championship Formula One races were held during this period. Also for 1952, crash-helmets were made compulsory; but these helmets were made with dubious materials and looked like medium-sized dinner bowls. ; 1954 : Engine specs amended to allow 750 cc maximum engine size with a compressor or 2500 cc for a normally aspirated engine. No weight limit.〔 ; 1958 : The use of commercial petrol became compulsory and alcohol-based racing fuels were no longer permitted. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「History of Formula One regulations」の詳細全文を読む スポンサード リンク
