Magistrates in Peterborough disqualified Ann Ruel for six months but were told she had told DVLA that she no longer wanted to renew her driving licence.
Ruel, who was not at the hearing, had pleaded guilty by letter to driving without due care and attention on Four Lamps Roundabout in Cambridge on January 21.
Prosecutor Lois Hutchings said it happened just before 12.30pm when Ruel was in a Volkswagen Golf entering the roundabout from Victoria Avenue. The cyclist was already on the roundabout, who had joined from Jesus Lane.
“She failed to give way to the pedal cyclist,” said Miss Hutchings.
“As a result the defendant has collided with the pedal cyclist, causing him serious injuries.” The court was told that the injuries included fractures, a dislocated shoulder and a collapsed lung.
"He spent ten days in intensive care in hospital and then three months as a wheelchair user. In a statement read to the court he said he twice thought he was going to die and during the incident he remembered the wheels going over his pelvis and it seeming dark as the car passed over him.
"The victim was unable to complete his degree as planned and had been due to start work in September. Ruel, who had a clean driving licence, told police that she had stopped at the roundabout and claimed she had a “clear view”.
“She didn’t feel her driving fell below that of a safe and competent driver,” added Miss
Hutchings. Ruel, of Abbeyfield Girton Green, Girton, informed the court she had not driven since the incident and had cancelled the renewal of her driving licence.
As well as the ban, she was fined £440 and ordered to pay £110 costs and £44 victim surcharge.
