The skidmarks made by the jet-powered Spirit of America, driven by Norman Craig Breedlove (USA), after the car went out of control at Bonneville in Utah, USA, on 15 October 1964, was nearly 10 km (6 miles) long. The longest skidmarks recorded on a public road were 290 m (950 ft) long and were left by a Jaguar car involved in an accident on the M1 near Luton, Bedfordshire, UK, on 30 June 1960. Evidence given in the subsequent High Court case Hurlock v. Inglis et al. indicated a speed "in excess of 100 mph before the application of the brakes".
