For a slightly different take: I want a car that runs on free software, that doesn’t spy on me.
Until then, I can bike, or continue driving my now fifteen year old sedan that I bought with 5% of my annual salary, used.
Similar reason for me. Although, as long as I could get a car without internet connectivity, I would even be fine with non-free software but even that is too much to ask nowadays. This also applies to gas or diesel powered cars though, so I will stick with my sedan from 2015 too, might even have the engine redone completely in a few years if there are no proper options by then.
For sure drive your car until the wheels fall off, but all cars have some kind of proprietary software on them. It is a big sticking point in the fight for right to repair. As far as free goes, Tesla and BMW are really the only ones being shitty about subscriptions and shit like that in their software. I have a VW ID.4 and never have to pay anything to use the software.
