As a useful method of controlling speed, I was somewhere recently where the municipality had nailed pilons onto the road to shrink lane width by ~1m. That is infinitely more effective than changing the number on the signs.
Caledon and Halton Hills are doing that. They're installing a sign (doesn't matter what it says - sometimes the speed limit, sometimes "SLOW", sometimes a pedestrian symbol) in the middle of the road, on the center line, and aligned with it but on the edge lines, another smaller sign. Of course this has zero effect on the actual physical width of the lane, and if you are aimed correctly down the middle of the lane it presents zero obstruction and you can carry on right through it without slowing down ... but it seems that about 80% of drivers freak out and slow to a crawl.
I know the signs have a flexible rubber mount at the bottom (they'll give way pretty easily when pushed near the top - I checked) but I also know that it's mounted between a couple of hard steel pieces bolted to the pavement, and I wonder what would happen if a bicyclist were forced off their intended course and hit one of them. I also wonder how resistant they are to the fabricated heavy-duty steel bumper of a truck ... or the blade of a snow plow.
let me extend an olive branch for you grannies out there - of course if you're competent and comfortable on your motorcycle you'll be much safer if you still mostly flow with traffic and avoid big groups of cars and speeding
but you should understand a big part of riding sports motorcycles for many is the ability to cut through the herd of retards that jam up highways never passing and tailgating each other
instead of making tiresome posts that essentially amount to "omg won't someone think of the children!?" try to keep that in mind
No.
I am on board with allowing lane-splitting in slow traffic. I'm not on board with extending that to someone blasting up the middle between two vehicles next to each other who are already doing highway speed.
