"Shipments of recreational vehicles to dealers have fallen about 20% so far this year after a 4.1% drop last year... Multiyear drops in shipments have preceded the last three recessions."
If you like DP imaging applications like this, this old Microsoft Research technical report is neat: it uses DP to merge frames from two webcams placed left and right to synthesize a view in the middle, like having a webcam in the middle of your monitor. The DP is interesting because it has penalities set up assuming planar content because faces are pretty flat and in front of the cameras.

How do you define "actually leaving"? Because after navigating to the portal, it occupies the whole viewport and becomes the main document with your site's URL.
Even if we assume you use AMP, package it with signed exchange, and Google SERP displays it then, yeah, your site could appear with no extra network request to your site. The lack of network requests isn't that different to old school HTTP proxies but with better specs and security. AMP has analytics and stuff so if you want to count visits, go do that.
I think the problem these technologies are meant to solve is making navigating between pages take under a hundred milliseconds and appear much faster by being able to preview/animate them. That would be good.
Yeah, new technology is not without cost and risks but Google turning the web into a walled garden isn't high on my list of risks.
The thing mentioned in the article sounds like it has more to do with the high ceiling height of one floor, not a whole building.
As far as I know most height restrictions are to do with casting shadows over other people's property.
For example, I own an apartment in a complex where some buildings exceed the area's height restrictions through an agreement with the government because the tall building is placed in the middle of the southern side of the block and hence only shades buildings in the same complex. If you're just building one building, that would be a problem.
Of course there are earthquake considerations, but everywhere I have seen them they're to do with choice of construction materials for a given size.
