The myth that you cannot enter or exit a DeLorean car if it's boxed between two vehicles because of it's signature gullwing doors. This video demonstrates that it's in-fact the exact opposite, and that the DeLorean gullwing door is far more practical than an conventional automobile door.
The reason this works is because the vertex where the door swings open is close to the center of the car on the top. If one were to place it at the side edge of the car, then it would be harder to get into than traditional cars. In fact, if you were to modify it so that it only had one door, but it's vertex was located on the other side of the car, then it would actually take up less horizontal space when opened.
