Right to repair advocates should be focusing on this too. Companies should have to provide a mechanism for disabling telemetry data (or some variation of this that I think we could discuss and identify) or provide opt-out that doesn’t affect other features of the vehicle so companies can’t play games.

I don't dispute that. But, I don't think owning the title means the car needs to be fully operational.

Titles to ratty, broken down, cars are bought and sold every day... aren't they? And, just because it's shiny doesn't mean it's a great car either. It could be a great sculpture.

I think the issues at play here are more about service and warranty contracts as well as buyer expectations. Having the title just means I own a giant hunk of metal and plastic, no?
