I actually asked once a long time ago when it mattered to me. The explanation was simple. How many 100 times have we been in traffic and seen a guy open a door to spit because he was dipping. Or, to get out to take off a sport coat.
Picture a motorcycle at 25-35MPH hitting the leading edge of a door. Your arm and leg would pretty much be gone.
That is why the shoulder was alright to use instead. I am with Ian on this one. Then again we come from the same area of the country.
For those that do split, do you agree that anybody that opens a door, it would still be your fault? IMHO it would be as all lanes were stopped.
