Why eat ramen noodles
Why not?

Yeah people usually do very very boring things while they are driving their car. We heard some of them are talking with the passengers, but this can be very dangerous as they might talk about broccoli or wooden floor. Some passengers also try to tell you how much they loved this 600 pages book about shower curtains! I mean come on, nobody can stand this kind of discussion, not even a ninja. This is why it's very dangerous to talk with people while driving.

But wait!

A true ninja has much better things to do. He will often end up cooking ramen while he drives his car. He will bring his portable stove and he will plug it in the cigarette lighter. But you are probably wondering where he will take the water to cook the ramen. That's no problem for a ninja because they always carry a 15 litres bottle of water with them, just in case they need to cook.
