Great Invention Idea

The premise is simple. You got a car, or you see a car? Then you know that cars are typically made of metal. Metal gets hot as is evident by say a stove.

So, why couldn't we create some sort of device that we could attach to a car that could cook food based on the amount of time driving.

Why would this help you? I'll tell you why person who definitely didn't ask that question. Because, you wouldn't have to stop to get food, it would be cooked specifically while you were driving? Is it a million dollar idea? Maybe. No. Possibly.
