BC hwys are/were horribly underplanned and thus, say, on the #1 eastbound from Burnaby to Chilliwackoff, there are only two lanes, not enough for all the drivers to stick to the RH lane and leave the LH to passers.
Thus not only the slow LH drivers, but you also get the Abbotsford Asslicker about three inches behind you who has absolutely no concept of traffic flow and thinks with sufficient application he will get there faster.
Same goes for Sea-to-Die Hwy.
God bless US 16 lane capitalist on-ramps to WalMart and KFC, thanks to a powerful lobby group for the car industry in the early days that bought out all the public transportation and convinced middle America that the suburb was the way to go (get's you away from all those darkies ) and that the car was an integral part of the family unit itself.
