People have often speculated on MSFS’s possibilities as a world simulator, with driving a car being one of the usual suggestions.
I’ve always thought the sim wasn’t nearly granular/detailed enough at low levels, with the roads (as in FSX/P3D etc.) often going sideways along hilly/mountainous geometry.
This video kind of supports that, and I have no idea how/if it could ever be fixed enough to be useable.
The only program I’ve ever seen that automatically kept all roads level was Outerra…
