At the moment this correct, minimal improvement would be noticed. However, maybe it could cause more people to actually hop on a bike and start riding...then think of the improvement in such a congested city as Toronto.
My main issue is the double standard with cyclists as has been mentioned before, filtering and splitting is deemed okay by society but not HTA for a cyclist, but yet for those on a motorcycle they are seen as reckless. They filter up and actually cause more congestion and the possibility of an accident as people now have to try and pass while leaving enough space.
I have actually begun to ask every officer I see about cyclists splitting and filtering in hopes that it will raise awareness and actually start cracking down on it (in my dreams I know). Since cyclists make up a large group of road users, I can only hope that they will also start to advocate for splitting and filtering and in turn help us.
I won't begin to lie to myself that it is for safety, yes that plays into it but c'mon, we all know we want to because we can. I would love to be able to filter so that I'm not stuck sweating my *** off on my way home hoping that my oil/air cooled bike doesn't give up half way and cause me to pull over (if you see a bike blocking a lane broken down, sorry, I'm not allowed to filter to make it to a side street and safely pull off)...it benefits everyone, and hurts nobody.
