- The door still impedes access/egress much more than a gullwing and, in some cases, more than a conventional door.
- The manufacture cost of the door hinge can be more than that of a conventional door.
- If the height of the parking lot ceiling is insufficient, the door may come into contact with it when opened.
- In the event of a rollover, emergency egress may be more difficult than with conventional doors, if not impossible.
