Elevators tend to be restricted to a specific group of people (inhabitants, customers, employees, etc.) in a way that public transport is not. If an elevator smells like urine, has suspicious stains or trash, chances are I'd look for an alternative. But it just so happens that the elevators I come across tend to be clean, unlike the public transport.
And I say this as someone who still takes public transport a lot, but it's increasingly less comfortable.
