NYT piece on fast driving and safety. My friend, Ian, almost cried he was so happy to read this.

raising speed limits to 70 miles per hour, and even higher, has no effect whatsoever on the death rates of young and middle-aged male drivers. That's right, guys: if you're under 65 and you find yourself cruising the great wasteland somewhere between Denver and Portland, say, you can rev things up with a clear conscience -- soon maybe even in Oregon, whose Legislature is considering upping its maximum speed limit from a poky, painful 65 to a brisk and wholesome 70.

Like most studies that seem to grant us leave to indulge our lazy, bad habits, this one comes with an asterisk, unfortunately, that it would be cruel not to disclose (despite the fact that as a young male Westerner I'd love to bury the finding in a footnote): higher speed limits do increase the death rates of women and the elderly. The scientists can't agree on the reason for this discrepancy, and if they're wise they won't try, lest they end up confirming the prejudices of people like my old high-school buddy who cursed every time a female driver of any age had the nerve to appear in the mirrors of his Chevy Nova.
