Apparently most people don't even change their own tires, if you figure
that 90% of women don't and that's 45% of drivers. Plus what, 10, 20,
30% of men. Of those who do, most don't even think of standing on it,
or, I suspect, are afraid to do so.

Of course there are very few flats these days so getting good data is
harder.
