Totally! I’ve heard that too. It’s like the grass is always greener on the other side of the release fence.
Definitely wish I had a Model 3! My parents’ Model S seems to check for updates regularly. Could just be the luck of the draw though.
I’ve noticed that too, nicholasbarber! Maybe Tesla’s just teasing us half the time? 
Just kidding, but it’s frustrating when they seem to play hard to get! Keep trying everyone!
