A quick glance at Look Around coverage in the U.S. seems like it's expanded outward in all current Look Around locations in my eyes. Well, I'm not sure about Hawaii, but the other areas seem like they've grown since the last time I looked.
No expansion on either of my phones, iPad, or Mac BTW.
I thought the same thing when I looked at Houston's coverage area in particular. It's coverage area was big to begin with...but I could have sworn I saw more. Wasn't sure if it was just my eyes! But at least I'm not the only one who thought that! (And other than the addition of Santa Cruz, I don't think the SF Bay Area coverage area has changed much since it came out. But Houston definitely seems to have been expanded. Vegas, LA, and NY...ehh, maybe a little, I'd say. Still waiting on the Chicago area, but I'll bet I'm like right on the edge of where the coverage will end, therefore I'll be right outside of the coverage area! I tried coming up with a rough estimate of the area covered by other Look Around areas and I'd say I have a 50/50 shot of making it into the Chicago coverage area when it comes out. If they're releasing it for like an entire metro area, then I'll probably get it since we are on the edge, but still considered to be part of the "metro area". But if they have a different method for how large of a coverage area, my odds will probably drop a bit).
And yeah, I had the "rest of the US" release on my phone as of this morning and then lost it a little while ago. It was nice while it lasted 😂 I got a quick chance to look around Alaska in prep for my trip, so I'm happy 😂
