In the megacities like Beijing, vehicle registration is tightly controlled to help manage congestion and pollution. EVs have more relaxed rules in those setups which provides a good incentive to get an EV.
Similar in a way to London’s congestion and ultra low emissions zones, except there the incentive is financial - you have to pay £12-15 a day to drive in them if you have the “wrong” vehicle type.









Qualcomm has its “IZat” system where:
- every AP’s BSSID your phone sees is sniffed by a program running continuously in the background, mapped to a latitude/longitude if possible (via GPS or any phone location means) and sent to their servers,
- So that other devices can send a list of AP BSSIDs and signal strengths and get a triangulated location within 5-10 meters.
So the server ends up with a global database of AP locations, and also the location of every device in the world using the service within ~5-10 meters.
They’ve had this in action since 2012.
