No, you’re wrong. I have a Tesla and service mode is free and amazing, I can look at any system and subsystems with it, look at logs, and do testing, all from the built in touch screen all for free. No other car manufacturer comes close. Not sure why you hate Tesla so much and are so bent on spreading false information. Maybe you should help save the planet and get one.
Tesla: Tarpening and Eberhard along with Musk’s cash changed the world. GM was a half hearted effort to please some politicians, as evidenced by leasing a few, and in the end destroying them all.
