Answer:
When you are inside me you will be encouraged to slam other cars.
I go around in circles, but always straight ahead, never complain, no matter where I am led.
Late afternoons I often bathe. I'll soak in water piping hot. My essence goes through. My see through clothes. Used up am I - I've gone to pot.
I am full of holes but still holds water.
I am gold and can be black and white I'm a symbol for a nation when freedom took flight.
No matter how little or how much you use me, you change me every month.
