"And nearly always with gullwing doors, too."
And there you hit the nail directly on the head. Here in the UK, in most car parks, once you get parked you will be stuck in the car. The parking bays are simply not wide enough to open those doors. You can't open a normal car door fully in those bays and with a gullwing door you can't open it a "bit" and slide out. You *have* to open it fully and if those pics are anything to go by, it ain't gonna happen.
And another thought just struck me. Those doors seem to go awfully high up when opened. I've been in some multi-story car parks where those doors may well hit the ceiling.
