A terrified woman was run over when she jumped out of a car driven by her jealous boyfriend.
She took the desperate action, after he beat her up and threatened to cut her body into small pieces.
Ashley Andrews told her he wanted to dismember her "so no-one will find the parts," Leicester Crown Court heard.
When she leapt out, Andrews tried pulling her back by her clothing and also continued hitting her, while still driving.
The victim (26) was dragged along Fosse Way, Syston, for 10 to 20 yards before he let go.
The car's back wheel ran over her head, causing her to lose consciousness and suffer bleeding on the brain.
Andrews (28), of Hardwick Crescent, Syston, admitted dangerous driving and causing actual bodily harm, on April 25.
He also admitted two earlier incidents of assault by beating.
Andrews was jailed for a total of two years and four months and banned from driving for three years.
Judge Philip Head told Andrews: "You're obviously consumed by ungovernable jealousy which, with drink, fuels your violence.
"You pose a long-term risk of danger to any female you're in a relationship with.
"Your victim has chosen to resume her relationship with you, notwithstanding what you did to her."
John Hallissey, prosecuting, said on March 28 the defendant threatened the victim with a 10-inch knife and held her in a bedroom for several hours, during a row about money.
On April 5, he accused her of cheating on him.
She went to bed but the defendant followed and "launched" at her, punching her jaw and pulled the duvet over her face and began to throttle her.
Mr Hallissey said: "She struggled to breathe but suddenly it stopped and he jumped off crying and begging forgiveness."
Andrews was arrested and bailed with a condition to keep away from her, but he returned to the home they were sharing on April 25.
He again accused her of cheating and at 7am struck her on the face with her mobile phone, breaking her nose.
Andrews then made her get into her car, which he drove to Watermead Park, where he repeatedly hit her in the face and ribs, before driving off, telling her he was going to rape and kill her.
Mr Hallissey said: "He said he would cut her body into small pieces so no-one could find the parts and then he would kill her ex-boyfriend and her sister.
"She believed the threats."
It was as he drove along Fosse Way that she began shouting out of the window and jumped out of the car, travelling at between 15mph and 25 mph.
A witness in a following car saw Andrew's back wheel go over her head as she hit the road.
She remembers waking up with a bloody and bruised face, with people around her.
The court heard Andrews has previous convictions for motoring offences and violence, including an assault on a former partner.
Matthew Smith, mitigating, said: "He understands he has issues to address and he's realistic about his fate.
"He knows he treated his girlfriend horribly. Part of his difficulty is his feeling of anxiety with relationships.
"His occasional drug misuse causes paranoia and his behaviour is worse after he's been drinking."
