Using Bluetooth mesh technology to create a network where each device sends an alert to the next device, until one of the devices is connected to the internet and that alert is sent to the network. Just like it's done with the Bitchat app.
Many times we drive a very long stretch without internet access, and important events happen on the road that we need other drivers to see. With this Bluetooth network activated, we can share with drivers near us, and they can share with those closest to them, eventually reaching someone who has satellite internet or even mobile data.
