The terrifying journey — which was captured in footage released by police — saw the victim hanging on for around a mile before he was finally thrown into the road.
His ordeal began when Grzegorz Musial clipped his wing mirror in a car park in Camberley, Surrey.
They exchanged details but Musial admitted having no insurance and said he would pay for the damage in cash, before getting back into his Ford Focus estate.
However, the victim was unhappy with this and said he would call the police.
Musial tried to drive off and hit the man, leaving him prone on the bonnet and clinging to the wipers.
Musial, 28, did not stop, instead embarking on a journey along the A331 dual carriageway towards the M3.
Witnesses reported seeing his car braking and weaving in an attempt to throw the victim off, police said. After Musial drove through a red light, the victim fell off. He suffered ankle injuries, a broken nose, and numerous cuts in the incident on October 14.
Musial was jailed for 14 months and banned from driving for 18 months at Guildford Crown Court.
