Road trip idea #1

I drove on freeways for 8 hours today and often I was driving next to the same three cars for an hour. So then I had an idea.

1. Everyone gets a Raspberry Pi that runs off a 12v cigarette lighter in their car

2. Every car-based Pi connects to a car’s stereo via Bluetooth and comes with a FM transmitter set to a different FM broadcast band for each Pi and you get stickers with your broadcast band to put on the rear window of your car

3. Tune your radio to any frequency you see on other cars then hear what everyone in that car is currently listening to.

4. It’s basically “sharing the AUX” with your fellow nearby drivers, but passively and wirelessly.
