Underground housing, underground businesses, etc. Would that be better for the environment + possibly save on energy costs? Also possibly safer in certain scenarios like tornadoes etc.

Potential issues that immediately come to mind are ventilation, earthquakes, and flooding. But it's not like underground dwellings/basements/etc. aren't a thing, so maybe those issues have been addressed in ways I'm not familiar with.

I think it would be great for a lot of our transportation to be underground. Underground roadways if needed, otherwise a much expanded subway system in cities

Road cause so many issues it's ridiculous. Have all the roadways and motor vehicles underground and only pedestrian/bikes up top with green spaces and public areas.
