Yikes! Even assuming it all works correctly and safely, who actually wants a steering wheel like that? What's the upside?
The only possible advantage I can think of is that when you start the car up again after having reverse parked, it'll be more obvious what way the wheels are currently pointing, so you can straighten up. But that's such a trivial problem.
Tbh I still think it's a bit of a silly idea. But it's not completely without its merits(the one done by Tesla was though - that was completely entirely pointless).
No, that just seems to be variable speed power assisted steering - so at high speeds it gives you little assistance, at low speeds it gives you loads.
With this it literally changes how much your wheel turns for the same amount of steering wheel/yoke movement. So at high speeds turning the yoke by 90 degrees will turn the wheels maybe 10 degrees so you don't kill yourself, but at low speeds the exact same movement will move the wheels 45 degrees so the car is a lot more manoeuvrable.
Oh I guess it's just that once you elimited the need to ever turn the steering device more than 90 degrees, it doesn't need to be a wheel anymore - same reason why bicycles don't have steering wheels but handlebars.
The yoke is to make visibility of the dashboard better. You can deal with rectangular screens easily then instead of needing to force things into a curve. Not necessarily a good enough reason, but it's not entirely frivolous.
