Sucks man, sorry to hear it. I used to lane split all the time in my L.A. days. I never had a serious motorcycle crash until I brought the bike to Minnesota when I started law school at the U. I had it in Minnesota for, no joke, 2 or 3 months before I smacked a deer with it, broadside, at about 75 MPH. Just be glad you walked away. Sometimes these things don't make sense, but I walked away too. My helmet didn't even hit the ground. Be careful. It's a jungle out there.
