If the house is on a larger tract, and there is plenty of unpaved ground, the water is more likely to drain off.
I’ve lived in two homes with basements that never flooded. Both had ground around them to safely drain off water. Newer developments have so much paving and are so dense, I think having a basement might be asking for trouble.

That's an interesting observation that I had not previously considered.
An advantage of additional spacing between houses is that it leaves more room to manage rainwater and it helps to mitigate the result of a neighbor who may have ignored that need.
Where I live, the soils are sand and that is a huge benefit wrt foundations shifting. A proper footer design gives a stable structure and rainwater mitigation prevents wet basements.
