If it doesn't save weight or work well then I recant.
I thought the point was that it did. Why include as an exclusive option on their Red Sport model if it hampers actual, measurable handling performance? It isn't listed as a luxury or safety option as far as I can tell.

If it sucks and/or it isn't an option for the Z, then I'm just wrong on that point, at least for this version of the technology.
Like I said, I am intrigued by the idea, but only see mention on it "potentially" saving weight, so if it's confirmed to add weight, please give me the link.
As to hydraulics and rack and pinion "all day every day", there's nothing inherently special about
any particular technology, so I'm fine with steer-by-wire so long as it works well. I'm not opposed to it (or for it) solely on principle or anything.
Engineers actually do usually know better than drivers -- although one hopes a good engineer will also take driver feedback into account when they engineer stuff.
When's the last time you composed a letter on a typewriter?
It won't feel tiny without having at least power steering -- which, BTW, is an engineered technology that adds weight and more mechanical interference between the driver and the act of steering the car.
It ain't a MX-5 or Fiat.
EDIT: Sorry, I must have misread that if you just were talking about the rear camera, rather than handling
On the camera: I dunno, personally, I like the rear camera, but I don't see it as any more or less necessary than any other item that improves visibility.
