You do not want to be on the same road as them if you are driving in the same direction. They think that they own the road, and sometimes even when they are moving very casually, they take over all the lanes. I have seen cars move into the opposite lanes just to pass them and then suddenly having to pull back in the lane containing the bikers due to cars speeding from the opposite direction. Then there was a lot of honking from the bikers, and fingers raised at the car driver. Luckily, no accidents or even confrontations as the driver then turned abruptly into one of the side roads to avoid any further confrontations.
Now I understand that there are road closures in Brooklin starting from Friday 4 AM to Sunday Evening. Had to go to see some clients in that area during this weekend. But it has been postponed as there will be nothing but mayhem on the streets and several cops patrolling!!
