>While occasional studies and columns on the topic burble up, what we need is a widespread education campaign. Perhaps we could begin with a graphic demonstration of how it’s done superimposed over the omnipresent “Road Narrows” signage.

I drive HWY 1 , on Vancouver Island, north bound from Victoria, encountering two fairly new merging lanes, both from the right at Leigh Road. Certainly for a while, tempers flared and some interesting displays of driving prowess were used. The most pathetic tactic was the operator of the motorhome straddling both northbound lanes, for quite a distance, passing both merge points causing a back up that day. I am sure the driver felt he was doing his civic duty stopping those pesky drivers attempting to merge from the right. 

Traffic flow has improved considerably after the Highways Ministry erected bold signs detailing the zipper procedure.  Mr. Wallace has also done much advocating for the zipper method as well.    

Better education is the key.
