This article I discovered on WCCO.com (or WDFL as some of us call it) finally ends the argument over traffic merging when a lane ends. Amr Jabr works at the Minnesota Department of Transportation and states, "We all want to be nice guys and merge right away but that's not really what we want. Merge at the very last moment possible."
This goes counter to what many Minnesotans do and is clearly an unpopular thing to do. According to the WCCO article, "MnDOT's research shows that 34 percent of us merge immediately, 62 percent wait for an opening and just 3 percent merge at the very end."
Who of us has not witnessed the meek Minnesotan merging as soon as possible and then getting into a rage when someone merges at the last possible moment? Minnesotans are bi-polar on the road--too meek to actually do what MNDOT wants us to do, seemingly out of courtesy; but when someone follows MNDOT's plan, but gets in front of the previously meek driver--you'd better watch out! That meek driver just became your worst enemy.
