Then you have the hill up the Snow Shed on the Coquihalla Hwy, speed limit 110km/h, semis crawling up the right lane at 20km/h, regular cars on the middle lane going 80km/h, then drivers on the left lane with capable vehicles screaming up at 110-150.
Except for the Snow Shed, I aim for a minimum of 10km/h below the speed limit when going up hills on multi lane highways.
