I have attempted to stay away from this thread, but this keeps coming up. I see a common thought here, that the speeders are saying that the people in the left lane going slow think they own the road. It boggles my mind. I don't get the people complaining about others thinking they own the road, then they go ahead and mention that cars should get out of their way like they own the left lane.....
No one owns anything or owes anything to anyone. This isn't Europe/Asia where pedestrians and vehicles are one and somehow magically juggle their way through a maze of each other. I've seen Cairo traffic and I wish it was like that here, but unfortunately it will never happen as long as we have such strict laws and the mindset/skillset of the public.
I admit, I speed on deerfoot, usually over 110km/hr. I consider myself really considerate on the road and since I worked the highways doing inspection for a while, I've learned to continuously monitor my mirrors. If I'm in the left lane, travelling at a speed that won't get me past the person on the right in a decent matter of time, I will speed up and switch lanes. I do this a lot on the QE2. However, I do have my exceptions. If the person coming up behind me has surprised me, meaning they were travelling at a really high rate of speed, I will neither hasten my pass or slow it down. You can't say I'm actually harming the safety of others moreso than speeders when doing this. Now, if that person behind me starts to blare on the horn, flash their lights, or do some extreme tailgating, then the foot comes off the gas a little. I'm not easily intimated and have a LOT of patience.
I don't do this for long though, as I have seen what these guys can do when they get a little PO'd. Specifically ramming the side of their truck against your vehicle and running you off the road, only to try to get a fist fight started.
Bottom line... be curteuous especially if the other person is as well. Telling a speeder to slow down because they are only saving 30 seconds can go both ways. Moving back to the slower lane to let others pass won't cost you 30 seconds either.
