I'd wager that women are taught to be aware of their surroundings for safety and men just don't ever get told, so unless there's an experience that teaches them, they tunnel vision.

Teaching situational awareness seems to be something that is lacking. Similar to critical thinking, I believe that there are skills we sometimes just don't get taught by our parents or natural experiences. These are things we hopefully learn over time, but having them called out while we develop isn't happening (I blame screens, but it's nuanced).

I tend to monologue to my kids when doing routine things, like loading the dishwasher (There's a big bowl over there that I need to save room for...) or driving (I can see a car on the on-ramp, it will want to be where I am in a few seconds, so I'm adjusting my speed); just pointing out things around me that have either a real impact or a potential one and why those items came to my attention.
