But I freely admit...I get a lot of entertainment both observing the differences and analyzing them, as this guy does in this hilarious video: A Tale of Two Brains - Men's Brain Women's Brain - Mark Gungor. Even if you don't find backing into parking spaces interesting, the video is worth watching...:) When I discuss this with guys, most of them I have talked to not only practice preemptive park positioning by backing in, and, they do it for much the same reasons I do. EXCEPTIONS: There are two valid exceptions that override the need to back in. First, when you can pull into the spot headfirst and park in a way that you may be guaranteed to exit headfirst. That is almost always preferable overall, as no backing up is needed to position the vehicle for later egress. The other one is posted signs that prohibit backing into spaces (Do Not Back Into Spaces). (Though I admit, I sometimes want to back in when I see them just to be contrary...but I don't.)
In that light, the act of prepositioning your car for a successful exit from any location while your brain, body, and vehicle are running optimally and working with each other at the best possible levels, is one of the most low hanging of the fruits of the reward tree of a minimally dinged car.
So now you are parked. When you come out of wherever you were, you might be severely distracted. Maybe it was a date. Maybe it was a movie. Or maybe it was a divorce lawyer's office. But your brain, and body might need some time to get back in synch.
You're still thinking of your ex-wife's lawyer playing a nasty child custody card. If you have to back out into a busy parking lot, your thought process might be "How the hell could my ex-wife stab me in the back like that?" while in the BACKGROUND your UNCONSCIOUS mind is saying "PUT IT INTO REVERSE. LOOK BACK TO YOUR LEFT. CARS? LOOK BACK TO YOUR RIGHT. CARS? LOOK DIRECTLY BACK. CLEAR?"''
That is the worst thing.
It is far better to have your conscious thoughts saying "Put it in reverse. Look back to your left. Are there cars?" and have your UNCONSCIOUS brain mirroring it: "PUT IT INTO REVERSE. LOOK BACK TO YOUR LEFT. CARS? but we know that isn't always going to be the case.
Therefore, you must habitually strive to increase your chances of a successful accident-free exit from the parking space by ALWAYS parking by backing in.
My favorite backing out story:
When I was going to college after I got out of the Navy, I was driving a 1976 MG Midget, my first car I purchased when I was in the USN.
I really fixed it up, completely stripped it down took out everything on the interior and had it repainted that piss yellow color because that was what it was, and I grew to like it. It was some kind of hardened paint called “Emiron”...it was a big deal for me!
Anyway, a few weeks after it was repainted, I drove it to college and backed in. Parking spaces were scarce, and there was on right next to me. This guy drove nose-first into the space, and there was about four inches between my newly painted car and his door.
Our eyes met, and the message I conveyed was clear: “Don’t even think of it.”
The guy looked straight ahead and paused for a second or two, then threw it into reverse (it was the shift on the column then) and floored it to back out of the space and totally t-boned a passing car!
Needless to say, I got out of the space I was in and parked elsewhere. I think that guy woulda keyed my car...
Basically, we men have evolved (or been gifted by our Creator with) better spatial and movement perception. As you say, a VERY fundamental difference in hardwiring. Two somewhat overlapping bell curves, but the vast majority of males have more brain area devoted to processing things in 3D and time/motion, just like women usually have more brain area used for emotional intelligence, nonverbal communication and pattern recognition as relates to gathering.
I think of it as a strategic option:
If it is somewhere I can easily back up with space and time to do so, then it’s less time to just pull in. If it is a situation where it would be dangerous to back out, then I’ll back in; the reason being that my visibility when backing IN is better than my visibility when backing out. “Visibility” both in the sense of what I can see and of being seen.
For me it’s always a calculation of the value of my time NOW vs value of my time after whatever brought me there, the stress of non-zero chance of accident due to the inattention of others given traffic patterns, and the need to maintain, test, and improve my spatial and time/distance observations and physical coordination (like parallal parking even when you don’t have to, just to stay in practice.)
