While I look forward to having an electric car someday, the trend in new cars does not look promising. Far too many instances of car companies having too much control, because of the advent of internet-connected vehicles.
Is there a solution to this? I don't know. Especially because I can see legislation cementing these sorts of practices in very much convoluted ways.
One can only hope competing car brands emerge whose competitive advantage is along the lines of "Your car, you can do whatever the fuck you want with it".
