This is an interesting video promoting why lane splitting is safer than not. What are your opinions, as riders?

I've found that in areas where Lane Splitting is common (California, parts of Europe), it has been a relatively stressless experience. Largely because the motorists in cars and trucks are familiar with, and not surprised by, a bike coming up between lanes. In places where it is uncommon drivers can have decidedly non bike friendly reactions which can make for a less than wonderful moment or two. I do not in any way blame the drivers of the cars for this, they are largely just surprised and react as surprised and untrained people do - i.e. randomly.

It all starts with education and must include the appropriate education and acclimation for both operators of bikes and other vehicles.

Exactly what I was going to say.

Here is a post about the same video, mentioning MbM, even.
He links another article he wrote, too.
