Don't know about driving the smart car slow. We're in Atlanta, if it's not moving between 70 and 80 mph, it's becoming some soccer mom's hood ornament. But I never worry that anyone is driving the car too SLOW. I think the only reason no one's gotten a speeding ticket in that thing is because the cops can't believe it was that car really going that fast, or they're laughing too hard to call it in.
Yes, it's ugly and weird and rides like a go-cart. Seems to think the 43 mpg even the way he drives is justification enough. Me, I prefer driving my 17 mpg pick up truck, unless I'm parking downtown. Some day, I'm really gonna see if his car fits in the back of mine.
