If you have a smooth belly pan covering up the under-body, you don't need
a large air dam. (Just some shorts ones for the wheels).

But normally, the underbodies of cars have all kinds of non-aerodynamic
junk hanging down in the air-flow..

So, sometimes, there is a need to keep the air flow off that junk..
