Mitsubishi (and others) in the 80s,90s had 4 wheel steering:

I never drove one; I had a friend that said it really didn't do much for him that he noticed.

Not the same as a full 90-degree rotation though.

I have seen large buses with rear-steerable wheels as you describe/link. It makes a little more sense due to the sheer length of the buses.

Doesn't one of the new mercedes have four wheel steering, but it refuses to be active during parking unless you pay a subscription?

I don't know if this is true or not, but I beg you, don't post comments like this. It's a question, and you could've spent the extra minute of research to _actually find out_ and post that.

This way we are left with negative value: We don't know any better, and instead are mentally burdened with speculation, that we have to actively work to not muddle up with what we know later on.

You can do better!

It would be a poor discussion that never had any questions in it.

True, but this was only a question in the grammatical sense. A discussion with only "questions" like these would be very poor indeed.
