It's based on Car2X/Vehicle2X data that's sent unencrypted and can be received with chips you can order from China.

Will be interesting to see how it fares when it does come to the US. It seems like there are some cars that already have the tech installed. But the US is allegedly more interested in the cellular version, which I am guessing is not as easy to pick up with a simple receiver?

My gut feeling is that this seems like one of those things likely to face a lot of backlash when it becomes widely known.

		I guess we only find out if some people order those chips and check if there is some data. From my understanding the idea is the same like maps showing air planes or ships (for ships it’s AIS). So without volunteers/pioneers who participate we won’t know. It seems like traffic lights and trams also can send data.
