I don't mind the rear door at all. I think it may be easier than opening overhead in a lot of situations. The overhead you must open, stand back, weight for hydrolic pressure to allow it to reach full height and then throw something in back. With the side opener, you could just open a foot, toss in gym bag, groceries, which are the two things I put in and take out the most and off you go. Quicker and easier I would think. I park pulling in a lot more than parallel parking.
I usually stand directly behind door to open and close, which means you're also sticking out in traffic some. And couple weeks ago, I was standing to the corner and pulled it closed as someone was talking to me and I bonked myself on the head.
