Doesn't look like that was caused due to lane splitting. Too fast, target fixation, locked rear tire.
I don't think newbies should be splitting live traffic lanes though, start with stalled traffic (aka read lights) before you start slitting through a giant traffic jam. And for the record, I'd argue splitting being legal is the majority (a lot of Asian, Europe and Australia..?? not sure on the kingdom of kangaroos).
@Roomie I used to split a lot and still scare cars, passing them by dropping 2 and pinning it for a split second. The worst reaction I've gotten is them swerving AWAY then honking. I can't imagine somebody stupid enough to swerve toward the loud angry noise that is passing them, that's against our instincts developed by evolution.
