My thoughts...
The problem with living in Alberta is that we're not a progressive province. As long as we're still extracting oil and gas out of the ground, any idiot in power can ride the economic coattails of this province's success and take credit for it. With all the royalty money coming in, the infrastructure in this province still sucks balls because of our backwards-thinking and fiscally irresponsible government.
Now before I start pissing patriotic Albertans off by shoving my political views down their throats like those crazy, Sunday morning TV preachers do with their religious views, I'd like to get back to my point.
What I'm trying to get at is that people are inherently naive when times are good. It's the "if it's not broken, don't fix it" attitude that everyone seems to have these days.
Growing up, I used to think that Canada was an innovative and progressive country that other countries looked to emulate but I'm learning that we're becoming more and more conservative like our neighbors to the South and I find myself wishing I lived in some of those more progressive European countries.
We need proactive leaders in this province who will see the benefits of allowing lane splitting and filtering. I just don't see any of this happening until we run out of oil and gas or people start taking politics more seriously and start demanding more from their elected officials.
Until then, I won't be surprised to see only one occupant in almost all vehicles (most of which are SUVs of course) driving to and from work during rush hour. It's an absolute shame.
You can probably tell where I'm going with this so I'll come straight out and say it. I support both lane splitting and filtering.
I have personally experienced lane splitting while down in California and avoided a lot of riding in less than safe conditions doing so. And for people driving cars who think it's unfair; grow up, stop being selfish and look at the bigger, long-term picture. Two of the many benefits everyone enjoys from lane-splitting are less congestion and less pollution. What more can you ask for? It's a no-brainer but unfortunately also an idea ahead of its time in most parts of the world.
Here is a great article on lane splitting by the way:
Lane Splitting: Tear Along Dotted LineSame thing with filtering. An absolute no-brainer but again, an idea ahead of its time, except for places like Spain where they now have specially-marked areas in front of crosswalks where motorcycles and scooters can filter through to when the lights turn red.

...and that's all I have to say about that.
