DANIEL Taylor already had 44 convictions, including a hit-and-run incident, before he killed Laura Entwistle.
Taylor, 24, of Ellesmere Port, had been previously banned from the wheel after knocking down a pedestrian on a pavement before driving off.
On the night Mrs Entwistle died in January 2006, he was driving home from a nightclub in the early hours of the morning.
He was doing up to 60mph in a 30mph zone along Wigan Road, in Bolton.
Pedestrian Mrs Entwistle, 44, was almost across the road when Taylor ploughed into her, Minshull Street Crown Court in Manchester heard.
She was carried on the bonnet for 50m before going over the top of his Rover 200.
Taylor spun the car round, drove back to see her lying motionless on the road, then drove off, the court was told.
Mrs Entwistle’s son Aaron, 20, arrived at the scene, cradling his mother until paramedics arrived.
But she was pronounced dead on arrival at hospital from “horrendous” injuries.
Taylor escaped justice for more than two years, covering his tracks by trying to torch the car on a disused railway line close to the Vauxhall Motors car plant in Ellesmere Port.
But a year after the crash, a tip-off led police to a witness who was in the car.
On the first day of Taylor’s trial last week, Christina Millar, of Bolton, told the court she had been in the car with him.
Taylor then changed his plea after hearing her evidence.
He admitted causing Mrs Entwistle’s death by dangerous driving and perverting the course of justice.
Taylor was jailed for six-and-a-half years and banned from driving for seven years.
