A young man who sped at people after a late-night street brawl in Collingwood, causing a crash that cost another teenager his leg, has been jailed for five years and faces possible deportation after his release.

Dieu Mawut Atem told police he was "as drunk as f---" when he took the keys of a friend's Nissan Pulsar and drove up and down a street after a large fight in and outside the Gasometer Hotel on September 2 last year, following a party for the launch of a record label.

Police believe 200 people were outside the venue and in nearby streets at the time, and many took evasive action as Atem sped up and down on the wrong side of Mater Street about 2.44am.

After a third U-turn, Atem crashed into the back of a parked car, which shunted into another parked car and crushed David Bilal Dada between the vehicles.
