Scott has the speed issue backward. A few years ago, we compared motorcycles to cars in a commuting situation. We had several pairs of people commute on the same route, leaving at the same time from the same place. One person in each pair drove, and the other rode. To make it completely fair, the motorcyclist had to put on a helmet and jacket and strap on any gear he was taking, while the driver walked to the car, tossed his stuff in, and drove away. The rules prohibited lane-splitting, but even so, the motorcyclists got to work, on average, 20 percent faster. A superior view of the traffic ahead, quicker acceleration, and the ability to squirm through narrow spots made the difference.
