Control
When you drive a car, everyone under your roof is putting their life in your hands, even if they don't say it with their mouth—it's still under your control.
It's really important to remember how many things are under your control when you operate a vehicle. It isn't just the people in your car either, it's everyone and everything in your way too.

You have to maintain control of your car or you'll hit a bunch of cats (かつ). The roads are full of cats at all times. And if you lose control of your car for just a second, you'll hit at least two or three cats.
If you don't want to think about hitting adorable cats with your car, you better maintain control. You're responsible!
