Saskatchewan plated Highlander through the mountains (rogers pass)in BC. He had to pass everyone, even if they were going above the limit.....only to slow WAY down for every curve. Then a passing lane would open up and away he'd go, at least 140+. Just to slow WAY down again once the twisties came. He was passing on double solids, in opposing pass lanes, and generally whenever it wasn't safe. Lost track of him from Golden on until just west of Banff where he roared past doing 140++, hopefully the law got him. That stretch is one highway you don't speed on!
I understand the frustration BC residents go through during tourist season. They simply don't know much about proper driving through the mountains, idiotic stuff like I experienced happens all the time.
