Context_1 : Synetic GmbH is a German video game company specialising in racing games. The company was founded in 1996 in Gütersloh by 5 former members of Ascaron.

Other motor racing series are not directly controlled by the FIA, although the Federation is the ultimate regulator for most international motorsport, and provides the regulations for many other series. The FIA's top motor racing events, known as World Championships, are positioned as the most prestigious titles within their respective fields, with Formula One considered to be the pinnacle of world motor racing. Context_3 : A racing helmet is a form of protective headgear worn by racing car and rally drivers. Motor racing has long been known to be an exceptionally risky sport: sudden deceleration forces on the head can easily occur if a racing car loses control at the very high speeds of competitive motor racing or the rough terrain experienced in rallying. A risk more nearly unique to motor racing is the possibility of drastically severe burns from fuel igniting when the fuel lines or fuel tank of the vehicle are jolted sufficiently to dislodge or breach them in a situation in which the driver cannot soon enough escape from his car. This happened to world champion driver Niki Lauda at the 1976 German Grand Prix race at the Nürburgring in a crash from which he barely escaped alive.
