“Londoner Tim Brady is now the new British national automobile speeding ticket record holder. Brady broke the old record by 16mph, by doing 172mph (277kph) in a 3.6 liter Porsche 911 Turbo ‘borrowed’ from his employer, a luxury car rental company.”
Cost Brady 10 weeks in jail among other things.
The fastest an American has ever been caught is “205mph (330kph) on a Honda RC51 superbike.”
