I agree that hot headed drivers wanting to go 90mph are part of the problem but Bob is also right. The newer passing lanes have helped a good deal but I have rarely, since 1993, seen the troopers citing anyone for delaying traffic. On a recent trip to Anchorage, spent 80 miles behind an individual who was driving at anywhere from 40 to 55 in the 55 mph speed zones, yet when coming into passing zones would speed up to at least 65 mph. This was very frustrating for about a dozen of us. Occasionally someone would have enough and pass 2, 3, 4 or more vehicles just to get out ahead of this idiot. This caused a dangerous situation but thankfully, no one got hurt. On three occasions, with at least a dozen vehicles trapped behind this person, saw troopers pass by in the opposite direction. I know that many are prone to blaming the tourists for these problems but the last couple of years, it seems, in my experience, that it is Alaskans that are causing the most problems.
