Go for the roller shutter door , I've lost count of the number of times I've pressed the button on our up & over and hit the car outside
Good job I paid the extra for the pressure sensative switch which cuts it out before any damage occurs - hopefully
Only thing to watch with the roller shutters is get an inside mounting one , so that you get the extra width between the pillars and how noisy it is ?
My old man had a plastic roller shutter door fitted and it rattles like mad when raising or lowering
