Please Explain Lane Splitting

I bought my first street bike brand new off the showroom floor at the Honda dealership while I was still a senior in high school. I've been riding that long on the street. I recently went down and visited my father and has a nice street bike. Those people down there have lost their freaking Minds! The police too! They're on a complete suicide mission down there in LA! Not me I'm not riding like that! Now honestly since I was there I went ahead and pulled forward at lights because I could, but I could have done without as well. And I'm the same way dirt bikes snowmobiles drag cars and Double Diamond runs at the ski slopes! But I feel safe doing that stuff compared to be on the roads in LA! On a motorcycle:realcrazy:
