A Doncaster man has been jailed for driving at 150mph – with four young children in the back of the car, not wearing seatbelts.
One of the tots was in the footwell of the vehicle, which was not insured.
Only seven other motorists in the UK have ever been convicted of driving at higher speeds, of between 155mph and 180mph.
Keith Millard, aged 27, of Moss Road, Askern, was spotted driving a Mercedes E320 by officers who were carrying out a speed check at about 9.35pm on September 14 last year.
Police followed the car from the A1 at Norman Cross in Cambridgeshire to the A14, where it slowed to about 90mph due to heavy traffic.
Officers were able to catch up and the car was pulled over close to the M11 split.
When officers got to the vehicle they found a woman sitting in the passenger seat, while in the back were six-month old twins in car seats facing forwards and not secured with seatbelts.
A one-year-old girl was asleep on the seat between the twins, and a two-year-old boy was in the footwell.
Millard told officers he was trying to get to Dover in time to board the last ferry to Germany, after missing a vessel in Hull.
Investigations revealed the Mercedes was Millard’s father’s, but the son was not insured to drive it.
Millard was summonsed to appear in court charged with dangerous driving and driving with no insurance, but he failed to show up.
After he did not attend the initial hearing he was arrested at Edinburgh Airport when he flew back into Scotland.
Cambridgeshire officers travelled up to Scotland to bring him back to the county.
He admitted both charges and was jailed for 20 weeks by a judge at Peterborough Crown Court.
Millard was also banned from driving for three years, and will have to sit a further test before being given his licence back.
He was ordered to pay £600 in costs and a £100 victim surcharge.
Sgt Gordon Murray said: “It is shocking to think of the danger Millard put these young children in.
“Not only would any collision, or loss of control, at such speeds have potentially tragic consequences for both the driver and other road users, but the effect on unrestrained toddlers would almost certainly have been fatal.
“It is only through sheer luck that no-one was injured or killed by his driving.
“This case should send a strong message that such reckless behaviour will not be tolerated by police or the courts.”
