Well, you're the one talking about a friend who takes many lives into his hands by doing this, so it's not about "loud exhausts." It's about someone who thinks so little of his own and others' lives that he'd be doing 200mph on a crowded public highway. Pretty much the definition os "reckless indifference to human life."
>> Story: a buddy of mine had a gsxr 1000 and would purposely screw with cops on the freeway and as soon as they’d light up he’d be gone and doing 200mph within a few seconds, fitting between cars easily. Within 30-60 seconds a bike can be damn near a mile away from a cop car. Radioing ahead won’t help if you don’t know where they went and they were never running a plate to run… most cops know it’s pointless to chase and often immediately call it off.
