Au contraire, my wife swoons everytime we see one, and asks (yet again) when we'll be able to afford to buy it. The efficiency is a very distant second consideration for her.
I have a neighbor trying to sell his Smart Car now.
$15K for a car that seats two, gets 38 MPG, and will vanish into a singularity in the event of a crash is anything but smart.
That's funny. You can watch all kinds of smart car crashes on YouTube, and while they tend to bounce and spin and roll, the inhabitants always seem fine. They have yet to post one where they vanish into a singularity.
Wait 'til the oil runs out and they run on red matter.
