An alleged road rage incident in suburban Toronto resembled a scene straight out of an action movie, a man who captured the incident on dashcam told CBC Toronto.

Daniel Yang's dashcam video shows a man dangling off the hood of a vehicle travelling nearly 100 km/h on Highway 404 on Wednesday morning.

"It kind of made me think of when you watch a movie and you see some guy doing a stunt," said Yang.

Dave Yeomans, the man clinging to the vehicle, recalled hearing the car's engine "revving underneath" him, and wondered how long it would take for the driver to "come to his senses."

Yeomans estimated he was carried on top of the vehicle for 500 metres before the driver "abruptly" hit the brakes, "I guess trying to slide me off the hood," he said.

'Didn't feel unsafe'

Yeomans said it all started when he refused to allow another car to merge in front of him. The other driver became incensed and started shouting profanities at him.

The two vehicles eventually came to a stop in a lane of traffic. Yeomans said the other driver got out of his car and threw a tool box toward him.

"Then he went back to his car, so I got out to take a picture of his licence plate and maybe him, and then he sped towards me," he said.

Yeomans said he jumped on the hood of the man's car so he "wouldn't get hit." He remembers thinking, "'Just hold on to the hood and wiper blades, and hope he doesn't swerve.'"

Yeomans told CBC Toronto that the experience "was a little strange," but he "didn't feel unsafe."

'Nothing short of unbelievable'

Sgt. Kerry Schmidt, a spokesperson for Ontario Provincial Police's highway safety division, called the incident the "most extreme type of aggressive driving I've ever seen."

Schmidt said police are searching for the driver, who could face multiple charges.

"[This] could have easily ended up as a fatality," he told CBC Toronto.

"Having a human body hanging on a roof or a hood of a vehicle by his fingers at highway speed down a provincial highway is nothing short of unbelievable and absolutely deadly."

Schmidt said the short fuse some people have on the roads is "completely unacceptable."
