One of the many great responses we got from the recent poll on filtering was a link from a SoCal reader by the name of Brian Leahy. Turns out he had previously done some research on the subject and then made a short documentary as a school project. I just got through watching it and was really impressed with what I saw. Not only is it beautifully shot but it goes into some really nice detail about lane splitting while also touching on safety, clubs, cops, and even retro bikes. There’s also some silly sweet footage of garages and workshops thrown in for good measure. See what you think…
