To be fair, I saw it a bit in Vancouver too, generally where the right lane is usually a parking lane in non-peak hours so everyone is used to the middle lane being the right lane, and therefore turn right from that lane.
Oh something I notice a lot on Fort Road is that people want to do 60 no matter what. 60 in a 50 zone, 60 in a 60 zone, 60 in a 70 zone, so I get passed in the 50 zone and held up in the 70 zone by the same drivers that passed me earlier. I don't get it.
I think bad drivers are a big city epidemic. Kelowna has been comparatively good. I hear Calgary is worse than Edmonton.
