Sounds like you almost kept up to him- keep practicing
I was behind a guy around 401 and Dixie, on what looked and sounded like a custom painted Ducati of some sort. Wasn't really able to get a good look because he was weaving and pushing the acceleration, with speeds topping out around 160.
He was 2 cars ahead of me by the time I got to Lakeshore and Yonge.
