I'm comparing to us interstates and not only grade but length of pull. I've driven all over the west and it is the worst and hardest on the equipment so far. Rockies are pure cake in comparison. Also the govt recently RAISED the speed limit on that hwy adding to the carnage. The mix of tourist traffic, tons of semis and coastal commuters on business mean the road is extremely busy year round. I've been caught in white out blizzards, pea soup fog , ice fog, hail and wind storms - all amazing since I rarely travel in the winter up there.
