"footprints of a gnat"

The most remarkable rear end of any car, ever. Never mind that this Honda FC concept is a fuel-cell-powered sports car, with the power plant mid-mounted, just as in Ferraris and Lamborghinis.

The chances of this becoming reality are as slim as a guitar string. But the idea of a future in which we can drive exotic machines with the carbon footprint of a gnat does seem enticing.
