First AJE, serious bummer! Sorry it happened, and heal fast!
I'm going with Weljo and Susser Tod on this - get a lawyer, the SUV deserves most of the blame.
But sorry AJE; while you had a right to be splitting, I have to call it contributory negligence: There was a big open spot to the SUV's right, and he dove for it - stupid, unnecessary, but drivers do things like that
Doesn't excuse his failure to signal, failure to look, or leaving the scene of the accident! - but it could have been anticipated.
For everyone else - I noticed that most non Californians (who probably have little experience splitting) condemned the act and blamed the rider.
I lane split commuting in Nor Cal for over 10 years without incident. I'm not a squid. I'm old, conservative, and careful. Splitting intelligently (reasonable speed differential, anticipating stupid behavior, wearing conspicuous gear (ATGATT), but still assuming you're invisible) is safe - probably safer than sitting in the middle of a lane in stop-and-go traffic, waiting for the distracted idiot behind to rear end you!
I don't expect to convince the non-believers, but I periodically filtered past CHP patrol cars without incident. (The CHP bikes were typically splitting much faster than I was - I got out of their way and waved as they went past. They waved back
Flip side is that splitting irresponsibly (and AJE wasn't) IS asking for trouble. But so is racing a motorcycle on public roads, wheeling down the highway, or exceeding your abilities.
Ride safe everyone! The moral here isn't about splitting, it's about watching out for all the bad drivers out there!
