A community driving app: Would you use it?

Had an idea for a very simple, hands-free, app that allows you to communicate helpful messages to other cars on the road while driving.

- “Your tail light is out”
– “your trunk is open”
– “your rear tire looks flat”
– “there’s something on your roof”
– “turn your headlights on”
– “you left your blinker on”

Without giving away too many details of how it would work – I’m wondering of this sounds like something you might use if it became ubiquitous, and many people were part of it.

Here’s how it might work: App is free. If you were part of the community of people using it, you might have a small sticker on your bumper or window indicating that you use the app.

You’d essentially open the app, press a button, identify the car you want to contact, and speak one of the preset messages (you can’t just say whatever you want – like an angry voicemail or something). The driver would get a notification, press “speak message,” and their phone would tell them “a nearby driver though you should know your tail light is out.”

Very simple and safe to use while driving.
