If the legal speed limit is 100 km/hr and I am doing the legal speed limit, which no one is supposed to exceed, why does it matter what lane I am in?  No one should be overtaking me.  My brother drives in the left lane all of the time at the legal speed limit and no one ever passes him.  He thinks it is because most people are law abiding, I believe it is because of the RCMP markings on his cruiser.  I guess we will have to agree to disagree.
