A Winnipeg driver says he is still in shock after he was involved in a road rage incident on Canada Day that was caught on video.

Roman Jestadt and his brother were driving along St. Anne's Road last Friday when they got into a verbal dispute with the passenger of an SUV.

"I don't know exactly why he got so mad. I think maybe at one point he was trying to pull beside me and then cut me off and I sped up a little bit," Jestadt said.

They eventually ended up stopped next to each other at an intersection. Jestadt said the man in the passenger seat of the SUV started yelling at him.

"I didn't feel like I did anything wrong," he said. "I rolled down my window and laughed at him because I thought it was a little bit hysterical ... then he spit on my window."

That prompted Jestadt to "give him the middle finger," he said.

"I don't usually do that, but it was kind of a natural reaction," he said. "Big wad of spit on my window, so I was a little bit ticked off about that. Probably shouldn't done that looking back now."

Jestadt said when they stopped again at another red light, the man in the SUV was so irate he jumped out and tried to smash the window of his car, repeatedly slamming his elbow into the glass.

Jestadt locked his doors and the man at one point tried to open the passenger side door.

Jestadt eventually drove off, but the SUV followed close behind and a high-speed chase occurred. Jetsadt said he eventually lost the other driver.

He installed a GoPro camera inside his car on the rear window last year for safety and insurance reasons in the case of a traffic accident.

Jestadt said he has shared the footage with Winnipeg police.
