Ours have hit numerous things - a street sign, shelves in my garage, the overhead garage door on a number of occasions. I've never had any trouble getting out of my Model S, even in tight spots. We're a thin family. Were you unable to get out of your driver's door when these people parked so closely to you?
Maybe my issue is because we have kids, so we use the back doors all the time, and load the car in our garage. This means that we deal with constrained door opening regularly, and I often have to duck under the canopy to go unplug the car and duck back to slide into the driver's seat. Also, our kids are old enough to buckle/unbuckle themselves, so it doesn't help us as far as leaning into the car and headspace. My mom and my father-in-law both have trouble getting into the back seat because there's nothing to hold onto when climbing up. Usually you at least have the roof to grab. In fact, my father-in-law can't make it back there, so he sits in the front passenger seat exclusively. We have a 6-seater and when we load kids into the third row (it's always kids back there), they just duck in and climb through between the middle row seats.
A fellow Model S owner brought up a new complaint to me the other night. He said he finds it "kind of gross" when he sees someone open their X door and you can see the whole person and "all their junk" in plain view. That one cracked me up.
I think I mentioned this before, but the only useful thing I've found so far is that they do a great job of airing the car out when it's hot. Given that I can use the app to cool the car off, this isn't a huge perk for me.
