As drivers, it always seems like the lane beside us is moving quicker -- especially when commuting during rush hour.
A number of years ago I did a piece for a television show called The Fifth Estate. In this piece I had to drive from downtown Toronto, up around the top of the city, and then back to downtown changing lanes as often as I thought I could to gain ground. In a one-hour drive, I made 60 lane changes while the other driver made only 20 and I arrived four minutes ahead of the other driver. So obviously changing lanes doesn’t gain much, I probably annoyed every driver around me, and it increased my chances of having a crash.
