It is hard to get in and out of the drivers seat of the Cadillac CT4 without hitting the rear hinge post of the back door. The steering wheel doesn't adjust up enough to clear enough space to get in without hitting your head on the top edge of the drivers side door frame. It shouldn't take contorting your body to get in and out of a car. If there was an emergency (ie: car caught fire) to exit the car, you wouldn't be able to in a hurry. I've tried my best to describe this nightmare.
