I learned to ride in the third world. Lane splitting meant survival over there, size mattered over there
. Here lanes are so much wider, traffic is so much more respectful of motorcycles. This here is paradise for lane splitting. Safe lane splitting.
BTW on the video on the first page of this thread, the door opening did not seem to me it was on purpose. Check the trunk lid of the car. It either came open and the driver wanted to close it or he had opened it and was getting out of the car to get something from the trunk. Much more dangerous are bicyclists riding past parked cars, they will open doors without looking.
