Revolve
If your car runs into a cloud you'll revolve around it instead of going straight through. Clouds are really hard to see through, so even though you're trying not to, you revolve in a tight circle up and around the cloud anyway.
Imagine driving your car around and around the cloud, instead of going through it. At least it's soft and cool.

You have to revolve around the cloud ten (てん) times before it disappears and you're able to go through.
Unfortunately, not long after you get through that cloud another one comes down and gets in your way. Now you're counting each revolution, one... two... three... all the way up to ten.
