Please Explain Lane Splitting

Ever driven in Mexico?
No, but while stationed in Europe, I drove in Italy and Greece. Lane splitting doesn't even come CLOSE to explaining what they do. On a two lane road, someone will just pull out and pass and both the person being passed and the oncoming traffic are expected to pull over while the passer drives down the middle of the road. CRAZY! Plus, They TOTALLY ignore stop lights and stop signs. They just bully their way through intersections while honking their horns.
