This discussion on speeding is fascinating. It's funny (well, not really), but a friend of mine was rear-ended last week on Glenmore (just past Elbow, approaching 14st). It's an 80 limit, which then slows to 50 and has a sign that says a 50 limit is ahead. He slowed in the middle lane to the legal limit, and was hit from behind by a driver who didn't feel it was necessary to slow down.
Since I'm on that route several times during the day, I've been very aware of when the police are out lately. In that zone, I never let me speedometer pass 55, and usually 50 when I'm near the construction workers - which, by the way is rare nowadays...are they finished that damn thing yet? But anyway, I've seen cars come up on me going so fast and then slamming on their brakes to avoid hitting me. It's ridiculous. Over the past two weeks, the cops have been there nailing seemingly dozens of cars at a time. As a full-time student, I don't have the funds to be paying double speed fines.
I must say, when I see someone blow past me when that zone changes to 50 ,and I see them just moments later pulled over to the side of the road by the men in blue, my day gets a little better.
