Racing

Auto racing (also known as automobile racing, motor racing or car racing) is a motor sport involving racing cars. It is one of the world's most watched television sports With auto construction and racing dominated by France, the French automobile club ACF staged a number of major international races, usually from or to Paris, connecting with another major city in Europe or France.

These very successful races ended in 1903 when Marcel Renault was involved in a fatal accident near Angouleme in the Paris-Madrid race. Nine fatalities caused the French Single-seater (open-wheel) racing is one of the most popular forms of motorsport, with cars designed specifically for high-speed racing. The wheels are not covered, and the cars often have aerofoil wings front and rear to produce down force and enhance adhesion to the track. In Europe and Asia, open wheeled racing is commonly referred to as "Formula", with appropriate hierarchical suffixes. In North America.

The sport is usually arranged to follow an "international" format (such as F1), a "regional" format (such as the Formula 3 Euro Series), or a "domestic", or county-specific format (such as the German Formula 3 championship, or the British Formula Ford). the "Formula" terminology is not followed (with the exception of F1).Board track, or motordrome, racing was a type of Motors port, popular in the United States between the second and third decades of the 20th century, where competition was conducted on oval race courses with surfaces composed of wooden planks. Although the tracks most often used motorcycles, many different types of racing automobiles also competed, enough so as to see the majority .

By the early 1930s, board track racing had fallen out of favor, and into eventual obsolescence, due to both its perceived dangers and the high cost of maintenance of the wooden racing surfaces. However, several of its most notable aspects have continued to influence American motorsports philosophy to the present day, including: A technical emphasis on raw speed produced by the steep inclinations; ample track width to allow steady overtaking between competitors; and the development of extensive grandstands surrounding many of the courses.The banking in the corners of board tracks started at 25° in 1911, like bicycles tracks were.

The banking was increased until 60° was common. The effect of the banking was higher cornering speed and higher G-force on drivers. Fans sat on the top of the track looking down at the racers. 1920s American national championship races contested at such venues.
