Ok, so we have Mr. Motorcyclist splitting lanes illegally, car driver gets irate, chase ensues and escalates into nuclear war and craziness on both sides. Nationwide lane splitting, I don't think so. Both of these idiots were equally in the wrong. Someone could have been killed from their antics other than themselves.
I disagree* that they're equally in the wrong. Yes, the rider committed what I assume would be a minor traffic violation in the beginning, but that put nobody in danger. And, since lane splitting is legal in CA, and is being considered to be allowed in other states now, I'd say his violation could be given even less weight.
From there, I feel like he really felt like he was running out of fear - Who would want to ride into oncoming traffic on purpose? Should he have to stop and confront that lunatic driver?
The driver on the other hand could've killed the rider, other drivers ... or himself (too bad he failed at that). Did you see where he almost slammed into the back of the one car?
Vigilante cager. He should do some time.
* Respectfully, since you have that sword dealio
