So true. I grew up/learned how to ride in the Bay Area. For me, lanesplitting is second nature. In fact, I have to remember NOT to do it in Ohio. It has an element of danger to it but the cagers are used to it. Just don't ride like a complete twat. Nobody pays attention to the CHP's speed recommendation for lanesplitting, including the police. In fact, I've had CHP motorcycle officers yield and wave me past at speeds of 65+. Having the ability to do this in California, along with reasonable year-round weather, (in comparison to Ohio) I didn't own a car for years. The traffic there is beyond stupid, but having a motorcycle allows you to bypass most of it. Although there is no law stating that you CAN do this, California has 2 vehicle codes to protect motorcyclists for lanesplitting. 1. Intentionally blocking or impeding a motorcyclist in a way that could cause harm to the rider is illegal (CVC 22400). 2. Opening a vehicle door to impede a motorcycle is illegal (CVC 22517). Not to mention doing this to a motorcyclist there may cause damage to your vehicle and or person. Because this does happen on a regular basis, the cagers really don't mess with the motorcyclists.
