I think it's obnoxious to call people "truly idiotic" if you would not apply the phrase to everyone who takes "unnecessary" risks. I am conditioned from childhood to wear a seatbelt in a car, but I also have owned a motorcycle in the past, and currently own a pre-airbag car (which I assume also lacks more subtle features like modern crumple zones and high strength steel, etc.). What makes one risk reasonable and another not?
