1961 Ferguson Climax P99: Antilock Brakes
The first antilock brakes were used to help bring airplanes to a stop after landing — by keeping the brakes from locking, steering control can be maintained. But the first widely acknowledged automotive use of the concept was this four-wheel-drive Formula One racecar that incorporated Dunlop's Maxaret brakes. Later, the mechanical Maxaret system was used on the 1966 Jensen FF. But it wasn't until the development of electronic antilock systems in the 1970s that such systems were more widely accepted. Now they're mandated by Federal law and fitted to every new car and truck.
