Vs what though? We're talking about a felon and addict channeling their risk-taking energy. I rode motorcycles exclusively as my transport in my 20s and it was one of the main things that checked use of intoxicants. You need your balance for a motorcycle and it uses the same risk-taking energy that many people would otherwise channel into drugs and destruction.

That is to say, those comparing car v motorcycle are doing the wrong comparison here. You'd be evaluating (car + substitute activity of drugs/crime/etc) vs. motorcycle -- rather than merely car v motorcycles.
