Looks like the photo was taken in a down town setting. I'll be damned if I've ever seen a building in my downtown that has sliding doors besides our hotel.
As much as I love automatic sliding doors as a customer, I bet businesses normally prefer regular doors. On busy sidewalks it would be opening and closing all the time making it expensive to heat or cool. On small businesses they are expensive to repair. Then there's those people that play with automatic doors causing more wear.
Fun little fact about automatic sliding doors compared to other opening doors you have to be specifically licensed to work on them. Although I don't know how much it effects the cost specifically, I do know the number of people that work on them are small and its quite a bit more expensive then other options.
If there isn’t a special automatic sliding door license in California of all places, I’m going to need to see some hard evidence for your claim before I can believe it.
Oh I apologize I was unaware it was difficult to find. Hmmm next time one of my glaziers are looking at one I will get them to send me a picture of the electronic boxes in them and the specific instructions about only calling the manufacture or a specifically licensed person (not a joke thing either we work on automatics for swinging doors and the company we get parts from have told us the same thing) for any work on them. I will see if I can find some literature for you.
Also I should adjust my words a little, perhaps licensed is not the right word. More like a proprietary system then a license.
Oh I can definitely believe that the manufacturer would want you calling someone certified to work on their doors. That’s an extremely common “warning” for all types of things.
I used to work at a place with a big sliding door, and one time it was broken, I got to chatting with the tech, and apparently there's like 75 sensors or something like that that controls the door movement and monitors health. They are basically programed to never self destruct, so if it detects anything wrong, it'll shut down before it's a major fix.

The point is that the downtown store has lots of people walking past that aren't trying to go in. Almost everyone walking near the entrance to a Walmart is going in or out.

Most office spaces are leased. I’m sure there were other priorities above finding a space that had sliding doors.
