Tar snakes are a nick name for the tar lines in the road used to patch cracked roads. They look black and a very slippery.
To my point: We practice safety skills like thresh hold breaking, looking into the corners, one or more fingers on the clutch/ brake levers all the time ect..... I suggest riding on the tar snakes.
For safety reasons, I practice riding on the tar snakes to become accustomed to the feel of it. Sounds dangerous eh? So is threshold brakeing in traffic.
What I suggest is try riding on a short tar snake at a time, to further minimize the danger, try it at 50 km, on a quite road, in a straight line. ( I suggest Renfrew st. from 1 st. ave all the way down to mc gill st. cause it's wide and can be few cars)
Why would I risk this your thinking? Have you ever accidently rode over one? Are you so paranoid of them in a corner that you freeze up when you see them?
Then you know they upset the bike a far amount, I suggest you practice getting use to them in a controlled situation.
