I don't really see how this could ever be better than what Google maps already does. It's neat and cool and stuff, it's just not useful. And you need a way beefier computer in your car to run it.
It may well be worse. This is one reason I didn't judge doing experiments to find out to be a good use of my time before vibe coding became a thing.
However, I also wouldn't bother with the full 3D rendering, I'd just use a normal map. There's several reasons why normal maps don't tend to include every bush, every letter box on every building.
