I also find Vancouver drivers pretty impatient and inconsiderate. I've come across people that don't seem to want to let you parallel park before having to pass by you; I've seen an accident and a lot of near misses because drivers are quickly changing lanes to get by people parking or making left turns. Other times they are utterly unaware of pedestrians.

Calgary drivers are no prize but at least people have enough courtesy to give a wave when you let them in a lane. I've rarely encountered that here.

I think its an extension of the how people are in general here. I find general courtesy amongst strangers is very cold compared to what you'd find in Calgary, so it probably ends up being that way on the road too.
