I saw these installed on the Arbutus Greenway today. This doesn't look in any form wheelchair, stroller, one wheel, skate board or bike friendly to me at all.
Is there any practical reason to build those barriers to justify making life harder for above mentioned groups?
I used to live across from a school in Edmonton. It was a 30kph stretch for about 600m, and the road narrowed from ~14.5m to ~11m, with cars parked on both sides of the road. Do you think cars slowed down? Of course not. And any mention of it on Reddit was an instant swarm of down votes from entitled people.
Cyclists are no different, a few bad apples spoil the entire barrel.
