It has been said before, on many occasions. Those studies were performed in places where lane splitting has been the norm for decades. It doesn't reflect the situation here, nor anywhere else if lane splitting suddenly became legal.
"Lane splitting" with a bicycle is nowhere in the same ball park.
This calls for driver and rider education imo. Taking approach of "we never did this here so we will ban it even though there are proven benefits for traffic and safety" is a bad approach.
Also, how is it not in the same ballpark?
Both are on 2 wheels. One pedal propelled one motor.
Width wise, motorcycle is a bit thicker but not by much.
Motorcycle is heavier, but once again it makes little difference if you roll by in a straight line.
As for speed, the way I see it done, it's done at low speeds. Bicycles are capable of going over the speed I can see bikes filter at.
