Richardson was linked to a string of other crimes
A man has been jailed indefinitely for running over and badly injuring a mother-of-four, when he took her car as she scraped ice from the windscreen.
Caroline Johnson, 46, was preparing for the school run in Langley, Slough, Berkshire, when Kevin Richardson and Karen Napper stole the vehicle in 2008.
Richardson, 34, was found guilty last month at Reading Crown Court of causing grievous bodily harm with intent.
He was told he must serve a minimum of seven-and-a-half years.
Napper, 37, of Ledgers Road, admitted aggravated vehicle taking and was jailed for 16 months.
The judge said Ms Johnson's family life had been changed irrevocably by the attack.
She is still in a wheelchair as a result of her injuries, which included multiple fractures, and does not know if she will be able to walk again.
After the attack she required a blood transfusion and treatment for cardiac arrest and spent two months in hospital.
Speaking outside court, Ms Johnson said: "It has been one year since the fateful morning that changed my life forever, but I am still here today and so grateful that justice has been done.
"Now I can move on with my life and put this stressful episode behind me.
Judge Stephen John said she needed help with most of her daily and physical functions.
"A huge emotional strain has been put on her marriage. Her family life has been altered forever," he said.
Det Insp Steve Armstead, Thames Valley Police, said: "Caroline Johnson is a very brave woman who was not willing to just stand by and watch two people steal her car.
Det Insp Steve Armstead: "It was absolutely horrific"
"Sadly, due to the actions of Kevin Richardson, she was seriously injured and is still suffering the consequences today."
Richardson, formerly of Chalvey Road East, Slough, had previously admitted aggravated vehicle taking, dangerous driving and causing grievous bodily harm during the carjacking on 2 December 2008.
Jurors found him guilty of the more serious offence of causing grievous bodily harm with intent, after hearing he deliberately ran Ms Johnson over and dragged her her 65ft (about 20m) down the road.
Drug addicts Richardson and Napper had been taking crack cocaine all night before they got into Ms Johnson's car.
Judge John warned Richardson if he did not address "issues" that made him such a dangerous offender, then he would never be released from jail.
Richardson was also sentenced to 20 months for aggravated vehicle taking and 18 months for dangerous driving, to run concurrently.
Napper was cleared of causing grievous bodily harm with intent and causing grievous bodily harm.
