It did fee like invading people in their garden, especially the satellite/3D view. But so do the photos: if you are politically exposed or a Youtuber, it’s annoying to know people can use the ad photos to disqualify you on poverty topics.
Using Street View probably whittled my list down by half, and saved a lot of wasted showings.
That way when you get there, you already have a little muscle memory that helps you know where to turn, which direction to head out of the hotel, etc.
If I'm driving somewhere new, I'll use it to identify landmarks for turns. While I'll often have the spoken map directions going on my phone, if the intersection is complex, streetview can help me get into the correct turn lane.
I wanted to use it for Germany prior to a trip a couple of years ago, but it looks like very little of the country has coverage, which is annoying. But it's their country and if they don't want camera cars photographing everything I can understand that.[0]
[0] I had a neighbor get divorced because of streetview. Back when it was new, the first thing everyone did was look up their home. Well, my neighbor saw a custom motorcycle parked out front that was not his.
I wonder whether you can use the percentage of blurred houses as a signal for evaluating a neighborhood.
Look at every country around Germany and you'll see a web of streets covered by Street View. In Germany it's one big blank [0] and what's covered uses decade old pictures taken before Google stopped mapping Germany on Street View.
I knew I took a right, and another right from the hotel and remember the style of the buildings nearby. I have the hotel reservation email, so I look up the restaurant every few years, just to reminisce.
Last time I did that, there was a different restaurant in its place. I'd like to stay positive and think the old guy sold the restaurant and retired somewhere nice with his wife.
I remember myself sweeping the Maps Satellite to find the pool, field in 2015 & many times after that, but no luck.
Just yesterday I scanned the whole neighborhood, about 10kmx5km for pool torquoise spots in Satellite view, found my pool in 5 minutes, & then spent next 20 minutes walking around virtually in Street View as well as internal panoroma shots, was amazing to revisit while on being the poo seat. Also looked at various roads approaching to it, where we used to drive.
Of course I starred the place in my list for future.
Streetview has a ton of info that Google Maps will never get quite right.
For work, we use it a lot to locate and assign accurate coordinates to health care facilities. Looking for signs with names or address numbers. We also use geocoding software, but that often approximates a location based on the range of numbers on a block. For example, the address 150 Main St might be placed in the middle of the 100s block. Works for cities and suburbs with regularly spaced buildings, but awful for rural roads where a "block" can stretch a mile.
Maybe this isn't as important outside big cities, but I like to have a plan of what I am going to do before I get somewhere. Otherwise, I might end up on the wrong side of the street without the ability to turn left, or I will be stuck in the wrong lane without a chance to crossover traffic by the time I see the turn in spot. In the city I am in, this means circling around and probably adding 15-20 minutes to the arrival time.
Another use case of mine, is when I have to go through an intersection of streets or freeways with a lot of merging and diverging routes, I use street view to know which lanes do I have to be on to not miss my exits, or what signs would I read if I am on the correct route.
So in summary, large visual hints.
It's also particularly nice for planning trips (I spent a significant amount of time "walking" my neighborhoods in Croatia and Montenegro before moving to each, and a good amount of time in Japan to plan out a ton of nice walks/views before spending time there.
I've also had a lot of fun (in VR and regular street view) "walking" through places mentioned in old parents/grandparents notebooks/diaries, where they lived/worked, etc.
Need to know the parking restrictions on that road, or the turning restrictions, or entry restrictions? Look at the signs on streetview.
Want to check the buildings you'll be turning at in advance, so you can make a short journey without looking at your phone? Streetview.
Want to know whether that street looks good to bicycle on? Streetview again...
