"With a width of only one metre, the Retriever can easily travel between the lanes of light traffic".
Yeah, right! The only way you can lane split with a Wing with any assurance of success is to cheat like him and have a rotating strobe light on a white bike. Then you
might get the space you need. Even the ST struggles and I only do it where the lanes are wide and the traffic jammed.
And I'll jump ahead of whoever and say you're welcome to your decision never to lane-split.
