I did read all of your sentences.

You says: “Lane splitting motorcycles and bicyclists are literally always illegal btw.”

Vs: “On August 19, 2016, California became the first state in the U.S. to declare lane splitting legal in an effort to relieve traffic jams.”https://www.shouselaw.com/ca/personal-injury/california-lane...

How do you square those two?

I guess the confusion is that you say it's always illegal then proceed to say it's sometimes allowed
