If one violates a statute (such as, it is illegal to drive drunk), then one is automatically contributoriy negiligent, depending on how that particular court interprets that rule of law(see, it's ambiguous, one never knows until one actually goes before a court how the court will rule). Courts will take into account ALL of the circumstances surrounding the crash, so it depends on whether the guy on the motorcycle's intoxication was a part of the cause of the crash. You don't like it, blame the legislature. (Again, this only relates to the civil liability of Lane. Criminally, he is eff u c k e d).
