I'm not sugessting in any way that the local residents along the Forks intentional speed once outside their area. But I also doubt they aren't any different than you or I, and will on occasion speed in their daily commutes. So therefore the same people that are doing the complaining are also guilty of what they are blaming others are doing.
What makes them so special that they are allowed to commute in other communities (whether it's for work or pleasure) and yet the rest of us shouldn't be allowed to travel on a public road through their community?
With regards to your comment about speed bumps being used in other communties. I agree with you that it isn't any different. In my opinion speed bumps should not be allowed anywhere on public roads. Ask any emeregency response personal what they think about speed bumps. They also become a maintenance issues over time and good luck trying trying to plow a road with bumps all over all the palce. If you think the solution to reduce speeding is by using speed bumps then why aren't they an approved standard in the Ministry of Transportation Geometric Road Design Gudelines, TAC guidelines, AASHTO etc. Speed bumps are intended for slowing down traffic in high pedestrian conflict areas such as busy parking lots. They were never intended to control traffic speeds for roadways.
The only reason they are being used on some roads is because the local vocal minority convinced their local councilors. Who most likey have no idea what they are supporting and only care about getting votes.
Everyone has a right to complain about traffic, but those same people doing the complaining should also realize that they also contribute to traffic in their daily commutes in communities outside of where they reside.
