Do you think Google is having someone go through the tens of thousands of street names?

Or do you think they had a team (on a completely different project or perhaps company) write a text to speech function that wasn't well suited for directions.

Streets have lots of numbers after all. People frequently have numbers in their name.

I could see that for Google Maps v1.0. I think we're past that point now. There's no reason they should still be using libraries suited to parsing the names of forgotten European monarchs.

They’re neither forgotten, unused, nor is it a nomenclature used exclusively by Royals; nor are all the Royals that use this fashion dead or out of power.
