Contrary to your expectations from a "despicable oilman", I have to admit I like Smart Cars. Or at least the idea of one. They remind me of a virgin in a whorehouse. A shining example of a more noble ideal, destined to fail after the fifth cocktail. The problem is, they have to coexist with huge Dumb But Safe Cars. In an evolutionary schema, these will procreate preferentially to the short life alternative.
As a friend says... "Dang smart... Until you die!".
Then it hit me. The real brilliance of the Smart Car. If you are guaranteed to die in what would otherwise be a fender bender, this represents a huge positive impact on your carbon footprint, in that it will stop entirely! Smart, indeed!
