I'm a Model S reservation holder, and have been for more than two years (yikes). I currently drive a BMW 5 series. I'm very much looking forward to my Tesla but the size of the car seriously worries me also. I can barely get my current car into my garage (and yes, in the middle of Berlin I'm lucky to even HAVE a garage, and ditto in SF where I used to live), and I have a small child that I ferry around whose door I can barely open once we're inside. I really do NOT have 4 extra inches to spare, width-wise, if I'm to be able to actually open the door and get my kid in/out. There's no way I can first stop and get my 3 year old out and leave her out on the street while I park. I don't care much about cup holders and so on, I do not find the BMW interior to be the be-all and end-all of luxury, but the simple size of the Tesla is going to massively difficult. If I street park then I won't be able to charge the car, not to mention the scratches and so on.
I really wish it was possible to get a decent four door sedan that's both comfortable and fun to drive and isn't a big hulking beast.
I know there's the future smaller/cheaper Tesla sedan down the line, but I don't want something cheaper (and slower and of lesser quality).
