I do it;
1. Just about every time in stopped traffic.
2. Depending on how much traffic there is, with average traffic to hardly any, I will do it most of the time in moving traffic.
When I am by myself. Why just "by myself"?
Cause most car drivers and motorcycle riders in Alabama have no idea on how you do it safely. Plus a lot of car drivers and riders in Alabama get all "butt hurt" when they see it done.
Plus, I have done it in front of law enforcement...and never gotten a ticket.

H.T.F. can that happen?
Done safe and right, it is barely noticeable. You are not speeding through traffic, you
flow through traffic.
I go typically around 10 mph faster than the traffic I am "splitting"...no more.
BTW, until recently, lane splitting in California was not "legal"...it just wasn't illegal.
https://www.ocregister.com/2016/08/23/motorcycle-lane-splitting-gets-green-light-in-california-but-rules-still-unclear/ At one time we had a motorcyclist on the site that grew up in California. She "split" traffic there and did it here.
She did get a ticket here in Alabama and after riding (once) with her I could see why.

When you "haul butt" every where you go, you attract attention...
