Design Bites: Buttons Behaving Badly

Rented a Honda CR-V yesterday, and when I went to the left side of the steering wheel to adjust the mirror I was startled by:

The dreaded "VSA OFF" button!

Which does what, exactly?* Must be important, since it's the largest button on the dashboard.

And while we're at it, does the icon in the circular switch say "mirror" to you? How about when you're doing 60?


* Turns out it shuts down the Vehicle Stability Assist system. Sounds like something you don't wanna press by accident.
