If it is true that...

Underneath cars offers cats a place that is high enough to crouch to walk through

and

Underneath cars offers cats a place where humans cannot easily get at them

and

Underneath cars offers cats a shelter from the elements

and

Underneath cars offers cats a 360-degree view

and

Underneath cars offers cats the opportunity to hide behind tires

Then it must be true that...

Underneath cars is the perfect place for cats
