Yet more data collection
Autonomous and driverless cars are nothing to do with what the general population want. This is everything to do with large tech companies (and Governments) to get yet more data from the unsuspecting public. This is just the same as Amazon Echo, Google Home and all to an certain extent Microsoft's half baked system. The more tech people blindly use (often with no actual reason other than it is fashionable or cool) the more they can monitorize you.
VW have been giving away a Bluetooth enabled thingy that plugs into the OBD port (there are loads of unofficial ones available already). This connects to you phone and collects all sorts of useful data but in order to use it you have to have a login to Volkswagen. All the data appears to be uploaded, trip information (yes it connects to Google Maps as well) fuel consumption, speed, braking etc.
Nothing comes for free and at the end of the day we appear to have a generation that happily share everything with anyone with no concept that what they are doing is in anyway stupid.
