As for the glamorization of taking risks, would you really want to take issue with that above all else? One of the first things that pops into my mind in this is the glamorization of street racing, like The Fast and the Furious and that whole genre. Talking about marijuana, coffee, hamburgers and the like, at least those things concern the health of the one person in question and that one person solely. Pose the worst case scenarios here, just for discussion's sake: an eating habit taken to an extreme -> obesity / drastically shortened lifespan, marijuana -> laziness / potentially shortened lifespan / wasted potential, [hard drug, coke or something?] -> shortened lifespan / diminished faculties / potential death by OD? Say instead you choose to go street racing, you careen out of control in a collision and go straight into a rusted out shitbox driven by a single mother of five, leaving her kids shit outta luck? I realize that example's taken to quite an extreme, but it was just to emphasize the difference between playing with one's own fate and doing so with someone else.
Now, be it as it may, there are outlets for serious and responsible racers and tuners. I don't know jack shit about those outlets, nor do I frankly know that much about the fuck ups (or cars and racing in general XD), but no matter how outraged and worked up I get when I hear about the consequence of a tragedy involving racing, I spare my rage from the sport itself and save it for the idiocy and carelessness of the wastes of life that waste their lives doing it so stupidly.
Just a little thought on food as well as some food for thought ;D
