A British driver with a prosthetic left leg who was clocked doing 125mph in his £300,000 Lamborghini Aventador told French police that his foot got stuck on the accelerator.
He was caught in a speed trap near Saulce sur Rhône, southern France, last Saturday as he headed towards Monaco for a rally.
A police spokesman said: “The driver initially said there was a fault but a mechanic checked the car — it was fine.”
