Is there a need for all wheel steering?

Sorry. I forgot to include the link. H/K is working on electric hub motors. I like that idea, but the 4-wheel steering as shown in the image seems overly complicated and almost useless.

Sweet. A Zero Turn car! Pull up to a parking spot, rotate 90 degrees, pull in.
Doing car ballet or interpretive dance maybe
You can park into a small space without hitting anything. But having parked in that very tight space, can the vehicle in front and behind get out without hitting you?
Add to this "unveiling" a point made by a car mag reader who claimed that car makers will design radical stuff and release photos as a matter of publicity.
He said this when Saab released photos of their "Variable Displacement" engine which featured a head which pivoted on one side to "raise the roof" of the cylinders to increase displacement.
The car in the OP's photo looks like way too much expensive, unnecessary machinery for most drivers.

The "need" is to add another upcharge to vehicle price.
Nothing new here. There have been, and are, a number of cars with four wheel steering, the most recent being the Cybertruck and the Hummer EV.
Although, that looks like a lot more angle of turn, both front and rear, than normal.

I wonder if H/K feels a need to be seen as innovators, rather than just a Honda Wanna-be.
I'm not sure about extra weight and complexity. With motors in the hub, axles and drive shafts are eliminated, and perhaps some complexity as far as transferring power to the wheels. More electronics and less mechanics? Might that not reduce complexity? I do agree with gimmicky.

I use my 2017 Subaru Outback Limited as an example. Getting on 190k and mechanically has been one of the best vehicles ever. I'm middle-aged and have a lot (1mil or more) of miles under me. I keep cars past 200k but also do my part with religious maintenance.
The result of increased electronic systems is lower quality "pleather" seating, trim, etc.. Issues know to Subaru that I have had...info screen goes dead; battery power from searching for 3G that doesn't exist; factory battery a group under what should be to power all the tech; cracking pleather seats; power window motor susceptible to water infiltration; and a few more I skate over.
The EyeSite system seems to work well but if you clean it or wipe it it is reported to screw everything up. How? I like my vehicles clean and in 190k haven't touched the windshield cameras. I also have to give it credit for a solid CVT. At 190k anything can happen; thus far it remains tight and responsive.
Off Topic: So much of tech is a Godsend but I notice more and more the tech we have has become cumbersome. I do not see price reductions in every day life but I sure do notice more and more tech is used to make ME do the work of customer service. Customer service has largely turned into contact us to help YOU problem solve OUR requirements. Airports, insurance companies, etc...the consumer does the work. Supermarket self check-out...list goes on and on.
electric hub motors, only when unsprung mass isn't important imo
I want to say Desoto or the like had something weird like the spare tire rotating and helping you into a parking space.
Every other manufacturer had some sort of gimmick at one point or another, H/K doesn’t want to feel left out.
Hondas had 4 wheel steering in about the late 80s. There were trucks with 4 wheel steering 100 years ago.
