The two-seat Smart Car apparently wasn't so smart, mainly because it barely had room for two people and was just too rickety-feeling to take out on the highway. Scion's new iQ has room for four, which may just be smart enough to make this pint-sized urban commuter-car work.
Just ten feet long, the iQ could be the ideal city transport module. It'll fit into motorcycle-sized parking spots and tuck into tight alleys and other places no other car - even a "compact" - could hope to negotiate. The Smart Car could do all that, too - but it barely had enough room inside for the driver and one passenger, which gave it about the same practicality as a motorcycle.
