This is becoming a growing concern for me. It now makes more sense why typical automakers historically don't offer updates, even when available, for their cars unless something is broken, the user complains, and it will be fixed with an update.
Tesla is getting to the point where there are too many models, with too many options, and too many configuration's to try and maintain a "global" release thats bug free and stable for all cars ever produced in roughly the last decade.
Don't get me wrong I love the constant updates, even though I prefer to replace my cars when warranty expires, but this constant improvement seems to be more then they have resources or are willing to commit to.
