officer, i realise i was doing well over a ton in that 30mph limit, but i am aware my car speedo has a 10% error, and i have been told by a friend that your speed trap also has a 5% error. So therefore i can get away with this
OK sir, i will report you to court for speeding and also a defective speedometer
