Another, equally annoying problem with swing out doors is their direction of swing relative to the curb. If you happen to be parked on the side of the road opposite to that of the swing (i.e. swing toward the road), no problem. If on the other hand, the door swings open toward the curb, then you have to:
1) add an extra amount of parking room to get around said open door when loading or unloading packages
2) accept that you might be at least partially exposing you and/or your packages to oncoming traffic.
Given the above PLUS all the other reasons stated, I'll take a hatch configuration any day.
