I don't have a whole lot of free space in my garage and always am extra careful to get the car backed in just right. About a foot clearance in front and two feet in the rear. No parking sensors so I just eyeball it and usually get it pretty close. I always walk around the front and double check before closing the door. Tonight I was in a hurry and had groceries in the back, walked straight to the back to unload and while unloading my wife was nice enough to close the garage door for me. Luckily I had backed in far enough, but by less than an inch. That was CLOSE!
