Yeah, first the reverse warning signal is going crazy the first few feet while I'm backing out. Then, the object that is closer than it appears happens to be a wall! I'm looking left and right at my mirrors like a maniac, going so slow that it takes a long time for the pucker factor to subside.
Normal size garage but my doors are not as wide as some that are available. Wish I had payed closer attention to that detail when I built my shop.
