No, some people ignore them just as some ignore other signs like no parking, no trespassing, keep out, do not litter, etc.

Yes, and there are always a few people who have behaved like that through out the history of humanity.

I've driven hundreds of thousands of miles in everything from 40 foot RVs to muscle cars, commercial trucks to Corvettes and Jaguars, in Canada and the US.

Well, that's good, but you said:

When and where can I see signs along town and city streets stating that driving 110 mph is disallowed?

You understand speed limit signs, right? You're just being a smart ass, right? :-)

Yes, and there are always a few people who have behaved like that through out the history of humanity.

And because of them and those who are worse, we have more and more restrictions, prohibitions and laws.

You understand speed limit signs, right?

Not only do I understand what the signs mean, I also know the reason why they are posted.
