I'll never forget what a professor said in college: If you're serious about eliminating traffic fatalities, outlaw seat belts and airbags, then install a 6-inch steel spike in the center of every steering wheel.

Still, over the years it's caused me to repeatedly notice that no matter how hard society complains about something (e.g., traffic fatalities), we keep implicitly deciding that some lifestyles are worth sacrificing lives to preserve.
