A builder caught travelling at 132mph was speeding because his pregnant wife needed the toilet, a court has heard.
Slawomir Adaszek, 30, was caught speeding on the A1 in Cambridgeshire in his BMW 745Li on 28 August, Huntingdon Magistrates' Court heard.
Adaszek admitted speeding but said his wife needed the toilet and he claimed to have confused kilometres and miles per hour on his speedometer.
The defendant, from Stanmore in London, was banned from driving for 21 days.
He was also ordered to pay a £350 fine, £50 costs and a £15 victim surcharge.
Representing himself, Adaszek said: "I am sorry. I know I have done wrong. This is my first time in trouble for driving."
The speed he was travelling at would have been equivalent to 212km/h. A speed of 132km/h would have been 82mph.
Pc Tony Barrios, casualty reduction officer for Cambridgeshire Police, said driving at such a high speed was extremely dangerous.
He said: "While modern cars are capable of greater and greater speeds, reaction times for us human beings have remained the same.
"It would take a car travelling at that speed the length of two football pitches to come to a complete stop and anything you do at the wheel is magnified by travelling at such a high speed.
"The chances of someone safely being able to avoid debris on the road travelling at high speed are greatly reduced - and officers are continually removing obstructions from roads."
