Not to mention we need places to park these buses. We should require every commercial location to have multi-level parking decks so that there is ample parking.

That's ludicrous. Think of the property values that would be decreased by thusly besmirching the precious skyline! Instead, we should mandate that people build out, wider & longer, rather than taller. Commercial locations should have parking lots for these microbuses (should really come up with a better name for them, too.)
