Ambient Alerts

This may work in the less-litigious UK, where the video was produced.  Here in the U.S. I'd give it six months before Honda gets hit with a class action suit from the surviving family members of drivers who had iPhones embedded into their frontal lobe after a collision caused the airbag to deploy.

Also, the stated premise is that "existing engine warning lights are easily ignored, and struggle to communicate how serious the problem can be."  Is it really easier to clip your phone to your steering wheel every time you get in the car, launch an app that ties the phone up and drains the battery, and glance down at the screen periodically while driving?  What happens when you need to charge your phone?  Now you have a cord strung between the steering wheel and the lighter socket, limiting your range of motion and potentially tangling up in your hands as you steer.

Also also, how often have you had a misfire on cylinder 2?  Ha!  Trick question!!  You have one right now, but you don't know it because you don't use Ambient Alert, and since you're driving while reading this you're ignoring a huge flashing red light on your dash.

I'm going to come out and say what we're all thinking:  This is a Bad Idea.
