I always back in, I'm always driving a full size Truck. It's much easier to back in than try and get in the middle of the damned spot every time. Easier to use my mirrors, and back up camera to get that bittch right in the middle.
I normally park out away from most spots. I don't mind walking a ,little.
Besides, I have a close friend that's a trainer for drivers. From Company cars, to trucks to semi's and straight trucks.
There is something like a 40% improvement in parking lot accidents when the driver backs in to the spot.
The prevailing premise is, you can clearly see where you're backing into a spot with your mirrors and, there are no issues with oncoming traffic or dumb shiit pedestrians, when backing in.
Not the same when you're backing out, you may or may not see oncoming traffic or some dumbshiit texting his girl or watching a fn tick tok video.
