smart cars?

I saw one of those little and tiny smart cars today. I am wondering why they call them 'smart'.  Here is a parable for you:
One day, at local a gas station, the owner of a bright yellow 'smart' car was laughing as he filled his car up for $12, that will last him a month and a half. On the other side of the pump was a big, beautiful, black SUV. The owner of that SUV filled his car up for $1,258.72, that will last him a week.  As they were leaving, the 'smart' car pulled out in front of the SUV. He was creamed and had to spend $58,987.42 on medical bills. The owner of the SUV, had to spend $1.35 on a box of band aids, because he was drinking a Pepsi and the can cut his lip when he hit a bump in the road as he was leaving the gas station. Pepsi heard about his injury, and in an act of kindness sent him a check for $12,000.
Who's the smart one now?
