Darwin and Car Evolution

Went jogging and there was that little dog, black and white, quite young. It wanted to be my friend, and wanted to run with me each round. It's name: Darwin. So I guess I should write something about evolution. Here it comes. It's about evolution of cars. There was this car, silly look, and too expensive. But it's so small that you can squeeze it into any sort of parking space, which is very useful. So they called it the SMART car. Then there came new generations of this car, still the same silly look, but somewhat more expensive, and unfortunately too big, so you can't park them anymore anywhere. Should these cars be called the DUMB cars?
