Autos.

Wheel was invented long time ago, at the same time as desire for speed in all its ways got created inside people's mind.

In our days, cars, for the most people, are more than just a fast transportation from point A to the point B. Some people spend lifetime creating and perfecting what long time before was simply transportation.

Some people admire cars, some hate them, some even collect great variety of them, but there is almost nobody who can totally disregard and refuse presents of the cars in modern society.
