+1 on this. 13 AAC section 2 (statewide "rules of the road") says you have to pull to the right if going under the speed limit (2.050). There's nothing in there about delay of 5 cars - that's a local thing, not a state law. Troopers will tell you that if someone's going the speed limit, legally they can't be impeding you.

Better solution is to change the law - must stay to the right unless passing someone, and no passing on the right at all. Flag both of those activities as "reckless driving". Then set realistic speed limits (most of the Glenn, Parks, etc. could be traveled faster than 65), and finally up the speeding penalties - say $20 per mph over 10-over, at 15 over it's 10 points and at 20 over it's vehicle forfeiture and license suspension.
