I bought a used Chevy bolt EV, for now I've pulled the onstar system fuse which kills the telemetry and GPS+cell antenna. No tracking with no power, it's my car and my battery so I decide what gets my power.
I'm not interested in letting any of these companies screw me over behind my back regardless of who is "less evil," but I've gotten so used to the convenience of EVs that I won't do without one.
I use my phone for navigation and music/podcasts and that still works just fine.
Might at some point look at a more sophisticated way of doing this like removing just the onstar module or terminating its antenna, but for now it's fine.
