I don’t really know much about that except for the fact that it does not have any form of a digital transponder that actively sends data it could be storing it though. Here is a site about vehicle privacy where I just looked up a random gen 3 Prius vin. (https://vehicleprivacyreport.com/report/?vin= JTDKN3DU1A000806#)
Yeah with EVs it seems like improving the privacy would be a pain, since they are reliant on parts of the digital system that is causing the privacy problem in the first place. I’m planning on sticking with a gen 3 Prius for awhile.
And that’s why I love old cars.
