A gunman remains on the run 24 hours after he opened fire on another motorist in an apparent road rage confrontation on the Gold Coast.

Police are still to locate the offender and the small silver hatchback from which the shot was fired.

The alleged gunman was a passenger in the hatchback.

A woman was spotted driving the car away from the scene on High Street at Southport about 12.30pm (AEST) on Monday.

The car has NSW registration plates CJO 06W.

"If a member of the public sees the car we advise them to immediately call police. Do not approach the car," police told AAP on Tuesday.

Police have interviewed the shooting victim, a boxing coach who says he was lucky his head wasn't blown off.

"I thought he was bluffing. Then he shot me," Ty Blyth told The Courier-Mail.

"I'm lucky he lowered the gun or he'd have blown my head off.

"He looked relaxed, with calm, cold eyes."

Mr Blyth has said he won't be giving evidence if and when his alleged attacker is caught because he fears for his family.

Police have described Mr Blyth's leg wound as a graze.

The bullet, which was fired from the window of the hatchback, hit Mr Blyth as he sat behind the wheel of his own vehicle.
