I think it is because people here are suddenly tough guys inside their cars! My guess is because they know if shit goes down they can always drive away.

I just had some guy that was driving crazy and almost hit me so I honked at him. He got all pissed and started yelling at me and actually followed me all the way home. As soon as I got out of my car and he realized I was way bigger than him and ready to throw down, he suddenly became all apologetic and said he thought I told him to follow me.... Yeah right guy was super tough until shit got real. See it over and over here; people are just tough guys in their vehicles....even down to old ladies flipping people off.

95% of people that say they would hit a lane spliter are just talking out their asses....and if they did they would never confront a person face to face...got to have that cage protection.
