Are you kidding me? "Chris sustained a broken hip, broken collarbone and internal injuries, but the teenager was dead. Chris denied he’d been drinking, and a Breathalyzer confirmed it. He also said he hadn’t been speeding, which was borne out by eyewitnesses as well as a police test on the tire marks."
How would you like such a jail experience, even without the horrors, for a mere accident? Especially one when some idiot jumped at you.
You speak more "as a cyclist who has to constantly contend with aggressive motorists" than someone clearheaded who evaluated the case.
And you know cyclists can do stupid things too like cut people off, turn unexpectedly etc, and cause accidents. In fact there are tons of "aggressive cyclists" who think traffic laws don't apply to them because they don't drive a car -- and kids who just want a thrill.
