HI i'm a newbie rider. i just had my first ride on the freeway 4:00pm peak hour traffic. i was just cruising on my bike like every other vehicle in traffic. there were at least 3 bikes that just lane split and made their way through the congestion. i'm a bit of a timid rider. But i guess i'll just get used to it and be able to read traffic and so forth .. in time. anyways what i really want to ask is What is the technique for heavy traffic riding? eg. lane splitting and looking for openings. flashing headlights? what do you guys do to keep things safe?
