Reading the translation of the talk, public transport vehicles have a persistent MAC but for private cars the MAC address changes every 15 minutes.
That still doesn't seem very private.

Found out about this today, up until now 802.11p hardware is very expensive, and so you cannot easily do anything with V2x messages like CAM or SPAT, but the fact this was done with sub £20 hardware is really interesting.
Cool, but it there's no links for more info, and it doesn't seem to work in the USA at all.
The project was shared as part of a talk at Graz Linux Tage. You can find it here, unfortunately it is only available in German https://media.ccc.de/v/glt26-688-c-its-mit-einem-esp32-ampel...

How does the hardware work? It seems like there isn't any radio hardware other than the ESP, so that can natively receive the ITS-G5 messages? Why not just use an ESP board with native ethernet then?
According to their presentation they are working on a rust firmware to do everything on the board.

The site is definitely lacking. It's half in German, half in English. The concept is that there is this protocol called ITS-G5, which is a European profile of 802.11p. Vehicles and traffic infrastructure can transmit telemetry on 5 GHz. Other vehicles and traffic infrastructure can use it for situational awareness. This website collects that data using local receivers and aggregates it onto a map, similar to what web…

The Germans and Danes and Swedes and Norwegians I see on the Internet developing and publishing software often have a better grasp of the English language than many born in the USA Americans.
That's true for Scandinavians, Germans are not as gut.

What about the traffic lights on the map do they also have transmitters?
In Graz, the city where the authors live, there are 165 of such signals planned.
