A Swiss motorist used his mobile phone to record himself driving on an autoroute near Geneva at 320 km an hour, nearly three times the speed limit, police said Wednesday.
But the offence was only uncovered six months later when the 28-year-old was questioned in another case and investigators found the images still on the phone.
Some shots were focused on the speedometer of his car, a Bentley Continental, according to a police spokesman.
Others showed the road, revealing where he was, and the phone’s timer recorded the date and the time — just before 3:30 in the morning local time last April.
Police said the driver, whom they declined to name, probably took the shots to impress his friends. His license was confiscated and he is free on bail awaiting trial.
