Both the code and the comments should be as understandable as possible. Don't forget that the effort to comment well helps the programmer in his/her own thinking and his/her own understanding of their own code, and helps in development of good code that doesn't have bugs.
My 2010 Prius has a package that includes parallel parking assist and cruise control distance limiter. In some fictional state (let's say 'private property') I tap my cruise control speed lever up and the car speed increases from 80 to 81.I tap this leve again and again, up to 83 mph. Then I tap it again and the car takes off without speed limiting. Tapping this lever down has no effect. The car is shortly up to maybe 97 mph. I repeated this many times.
One doesn't think of things like putting the car in neutral instantly.
The natural braking action does disable this effect.
