• This test borders on meaningless, but measures random gearhead knowledge, how (or if) high-performance cars, boats, planes, you-name-it work… If you do well you shouldn’t be particularly proud of yourself, because you’ll know there are a zillion ways to improve the score, and if you do poorly you shouldn’t be especially chagrined, you’re just not a gearhead – no shame there. Many of the world’s leaders aren’t gearhead’s either, although they’d be far more trustworthy if they were.
