Literally nothing could get delivered to me if they used a Google Maps address bar. My address just didn't exist at all to that search bar. It could be found on maps, just not on that little search bar widget.
I ended up just putting my neighbors address and either intercepting delivery drivers or putting in the notes that I was at the half address next door.
Moral of the story: check your potential address BEFORE you move in
We have had solicitors walk through our side yard convinced they are going to the 1/2 address (which we don’t have).
Maps seems to show them all correctly.
A lot of problems would just be solved by trust-but-verify information. If a user wants to put non-sense in a text box, that should be a 'them problem' but a service that presumes all email address end in .com or that a user doesn't know their own address is worse. With that said, I understand why services do it because the Venn diagram of "will type non-sense into a field then wonder why it didn't work" and "will email into support and be the reason someone drinks" is largely a circle.
