You've gotta be referring to escalators here. Never seen a moving walkway in a big-box store, or a subway station for that matter.

I do think a concept with parallel tracks moving at different speeds would have been easier to use and more reliable though. But it might not have been revolutionary/over-engineered enough to attract attention and subsidies.
Speaking of speed, in the Stockholm main station the escalators go faster than others I've experienced... But I don't know if they've adjusted the speed since my experience years ago.
I have seen some occasionally in stores, in or around Paris. They usually are on an incline to allow trolleys to be taken up or down a level. Or similarly outside malls to get trolleys to the upper level of a car park. That’s in places where you have to stack car parks instead of just having them sprawl all over the place, of course.
> or a subway station for that matter.
There are a few of them in Paris métro stations. Some of them in the London Underground, as well.
Quoting wikipedia:
> The walkway has been the longest continuous moving walkway in the world since its construction in 1961.
I have never seen a flat one in anything else but airports or connections between other mass transit transports such as metros and trains. Definitely not in big box stores as they would be inconvenient and slower than pushing the trolley in the flat.
My mental gymnastics is mostly trying to mobilize an entire city with the concept. I see some research suggesting there is lots of room between walking and driving distance. Bringing a bicycle also has its down sides.
Because getting on and off is already so difficult one tends not to notice the other problems with the tech. A simple crossroad is already a problem.
Moving fast is no issue for the more athletic passenger without luggage. It is also the most useless device to them. People with mobility issues don't have to get on but they do have to cross the road.
You would want to slow down or stop the surface, put a fence around it, you would want chairs, a roof would be nice, perhaps walls so that you can further control the climate. And then you have a bus, metro or tram. (haha)
One cool variation (not my idea) was to have a moving platform fromwhich to get in and out of a moving train, tram or metro. You could also make vehicles that connect on the sides. Those would have lots of fragile moving parts and potential dangerous situations if they fail. I see a night train misaligned with the station one time with the last door opening above the entrance of a pedestrian tunnel. A drunk guy almost walked out into the 5 meter drop. That seems preferable over falling between two moving trains.
