I was backing my wife's car out of our driveway when I realised I wasn't watching the backup camera, nor was I looking out of the rear window. I was only listening for those "audible proximity alerts" - the high-pitched beeps that my car emits as I approach an object while in reverse. The problem was that my wife's car, an older model, doesn't offer such beeps.

I had become so reliant on this technology that I had stopped paying attention, a problem with potentially dangerous consequences.
