If you only have one then I especially don't understand what kind of compromise you need to make in relation to the floor space. It's the most efficient transit vehicle with regard to space, folded or not. Your use case is ok, I have a friend that does something similar when his wife takes their car for the day. But even without a folding bike it would be trivial to put a rack for the bike on the back of the car. Take care.
