In this specific instance, it sounds like an "extra" and not a "change". So, I would be okay with that. However, I don't own a Tesla so I can't say for sure. For me personally, I don't want upgrades that throw away all my muscle memory in the name of "design". As more and more people enter the software development ecosystem, they're going to need to learn (the hard way) that sometimes "boring" is the right thing to do.
The update also apparently changed the dashboard and rearranged common things like your current speed.
The difference is that for their new features like autopilot, you actually pay for the upgrade like DLC.
