A ROGUE P-plater photographed hurtling down a Melbourne freeway with both legs outside the driver's window has come forward to police.

Police said the man had "made contact" with them, but they would not elaborate on whether he would be charged with an offence.

More inquiries would be made this evening, a Victoria Police spokeswoman said.

Police had earlier appealed for the driver to turn himself in, saying they had identified the owner of the vehicle, and that they would be coming for him if he did not front a police station today.

Shocked motorists snapped the “ludicrous” Volkswagen golf driver literally putting his feet up as he cruised down the Eastern Freeway, near the Blackburn Rd off-ramp about 7am on Christmas Eve.

Inspector Bernie Rankin from the Major Collision Investigation Unit said the incident was "no joke".

“This young man, his behaviour without any further examination is conduct endangering life - that’s a very serious criminal charge,” Insp Rankin said.

“You might be thinking it's funny or it might be a joke, or you might be showing off in front of your friends, but at the end of the day if you hurt someone or if someone sees what you're doing...so just remember that.”

Motorist Stewart (last name withheld), from Heathmont, photographed the driver speeding down the Eastern Fwy on Monday morning.

“I couldn’t believe what I was seeing. I thought: if his right foot’s outside the window, how is he accelerating? Then I saw both feet out of the window and I thought: bloody hell,” Stewart said.

He said he saw the driver travelling over the speed limit before he pulled up next to the packed car, when the driver pulled his feet in just before the EastLink tunnel.

“He looked very young. This guy’s a risk to my safety. I don’t want to share the road with people like that,” Stewart said.

Insp Rankin had earlier said: “The local police will be following this matter up, and what I’d encourage the driver of that vehicle to do - his vehicle and his images have already been on the media - I’d suggest he walk into his local police station and speak to us, because we’re certainly in the situation where we know who is in charge of the vehicle.

“We’ll certainly be knocking on his door if he doesn’t present himself today at some stage.”

The legless driver isn’t the only example of reckless behaviour on Victoria’s roads this holiday season.

A woman was photographed reading a book while doing 100km/h on the Monash Freeway last week.

“This is a constant in your face reminder that there are people out there who just don’t listen and don’t really obey the law,” Insp Rankin said.

“We’re really horrified with the toll: five dead since Sunday. All of them…avoidable collisions and, really, if we don’t slow down and start doing the right thing this is going to be a horrendous Christmas-New Year period for us.

"We’ve got to really get the message out there people have just got to slow down.”

Insp Rankin said the man's “selfish behaviour” meant he would be unable to control his vehicle in case of an emergency.

“Assuming he was on cruise control - which is an assumption - he couldn’t brake, he couldn’t stop the vehicle; he’d even have difficulty turning the wheel, so absolutely ludicrous behaviour.”
