The full Mulsanne Straight is a whopping 6km long, and by the late 1980s, cars were reaching speeds of over 400 km through this part of the track. In 1990, race authorities stepped in to prevent a seemingly inevitable accident, adding two chicanes to create three, 2km straights. Straights longer than this are now banned in global motorsport.
