no roads are designed for splitting, have you seen the roads in Europe or Asia?? everyone splits / filters there, and bad drivers are every where not only in Toronto, saying that we shouldn't legalize filtering or splitting because the drivers are not ready for it is like telling a virgin not to have sex because he / she will probably be bad at it the first time
So you are suggesting "well fook it, let's do a free-for-all instead of improving driver / rider education programs to address some of the issues that are apparent". Yea, sounds like an awesome idea. And I've seen plenty of roads in Europe and Asia. Difference is that while bad drivers exist everywhere, the driver education courses are a lot more thorough over there. For Asia... well, I've seen plenty of videos of car crashes and motorcyclists getting splattered... it's like their version of "America's Funniest Home Videos"... tons of weekly submissions.
