Not to re-energize an old debate or re-open old wounds (yeah, right!:green_lol
but the current issue of Motorcycle Consumer News carries an article that uses Federal Highway Administration (FHWA) data on rear-end motorcycle accidents to compare states with similar riding conditions: CA, AZ,FL and TX; as well as US as a whole.
Of these, of course, only CA allows lane-splitting (also called lane sharing). The author of the study seems pretty convinced that the practice reduces rear-end crash fatalities, both from the motorcycle being struck from behind and when the bike strikes a car in the rear. I won't try to present all the numbers, but corrected for the number of riders (per 100,000 registration-years) CA deaths are a little over 1, AZ almost 4, FL 3, and TX almost 3. For the US as a whole it's 2.5.
A lot of the objections to lane-splitting seem to center around the idea that a biker might get sideswiped by a car changing lanes. But this isn't really the greatest danger for two reasons: 1) a glancing blow is not nearly as likely to be fatal, in part because 2) lane-splitting takes place under conditions of slow or stopped traffic --i.e., low speed.
Compare this to getting rear-ended by a soccer mom in an Escalade texting the pool boy to arrange the next romantic tryst and you will see why fatalities involving a bike getting rear-ended are fewer in CA. Likewise the numbers of fatalities are lower for incidents involving a bike rear-ending a car -- not so much lower, but also statistically significant. And again this is logically due to the fact that the biker is alongside a car which stops or slows suddenly in traffic instead of directly behind it.
I know this will not convince doubters. But then, nothing will.
