Unintended Consequences ⇥ rantbox.io

Matt Henderson (via Michael Tsai):

When I switch my Jeep off, its headlights remain on for about 30 seconds. Presumably this was done under the assumption that you’d appreciate the lights in a dark garage, as you make your way to the door.

I’m never quite sure myself whether I actually turned the lights off or not. And so, inevitably, I end up delaying my departure from the vehicle for the 30 seconds or so it takes to confirm that the lights are actually off. (And you can imagine that bystanders find that—a guy staring at his car, with its lights on—equally odd.)

How would you know if this system were to malfunction?
