Not sure if this is even an issue where you are at, but here we have odd even parking from like Oct 1- May 1. Where on odd days of the month you park on one side and even days the other....for easier snow removal.
I would call and file a report/complaint about the parking you in aspect though. For one, it seems a little like harrasement and to by parking so close they make it impossible to get out...Pregnant or not emergencys happen. I might be understanding things too, but just because you have a driveway doesn't mean you must park in it. Or at least here you don't have to. So I would make sure that the ones parking you in understand you dont' need to use it...
I know not much help.
Good luck.
