The trend was sparked by Sega's "taikan" games, with "taikan" meaning "body sensation" in Japanese. The "taikan" trend began when Yu Suzuki's team at Sega (later known as Sega AM2) developed Hang-On (1985), a racing video game where the player sits on and moves a motorbike replica to control the in-game actions. Suzuki's team at Sega followed it with hydraulic motion simulator cockpit cabinets for later racing games such as Out Run (1986). Sega have since continued to manufacture motion simulator cabinets for arcade racing games through to the 2010s. In 1991, Namco released the arcade game Mitsubishi Driving Simulator, co-developed with Mitsubishi. It was a serious educational street driving simulator that used 3D polygon technology and a sit-down arcade cabinet to simulate realistic driving, including basics such as ensuring the car is in neutral or parking position, starting the engine, placing the car into gear, releasing the hand-brake, and then driving. The player can choose from three routes while following instructions, avoiding collisions with other vehicles or pedestrians, and waiting at traffic lights; the brakes are accurately simulated, with the car creeping forward after taking the foot off the brake until the hand-brake is applied. Leisure Line magazine considered it the "hit of the show" upon its debut at the 1991 JAMMA show. It was designed for use by Japanese driving schools, with a very expensive cost of AU$150,000 or per unit. Advances in processing power have led to more realistic simulators known as sim racing games on home systems, beginning with Papyrus Design Group's groundbreaking IndyCar Racing (1993) and Grand Prix Legends (1998) for PC and Gran Turismo (1997) for home consoles. Occasionally, a racing game or driving simulator will also include an attachable steering wheel that can be used to play the game in place of a controller. The wheel, which is usually plastic, may also include pedals to add to the game's reality. These wheels are usually used only for arcade and computer games. In addition to the myriad commercial releases there is a bustling community of amateur coders working on closed and open source free simulators. Some of the major features popular with fans of the genre are online racing, realism and diversity of cars and tracks. Research Driving simulators are used at research facilities for many purposes. Many vehicle manufacturers operate driving simulators, e.g. BMW, Ford, Renault. Many universities also operate simulators for research.
