Maybe it's just the angle of the picture, but that front picture makes the rollaway door seem too narrow to get a car through. It looks no more than twice the width of the standard entry door right next to it. Unless this is a garage for lawn mowers?
It might not be an issue, however as it doesn't look like the rollaway door even opens so most guys I think are going to be cutting the door out anyway to have something either in or sticking halfway out of it.
