Do you like driving?

Today someone asked me if i want a car. It makes me think about why I need a car.
Personally, I feel that driving is something dangerous, and it makes people tired. So I always choose to take the subway or bus to get to somewhere. And also driving is not so healthy for people because they have to stay in the same position for a long time. So, do you agree with me? :)
But I like the outer appearances of cars.  I like cars that look really cool !
