I really enjoyed reading this thread!
My husband (INTP) was wondering why I was sitting at my computer with giggles periodically breaking out, so I had to read it to him as well. We definitely can relate.
Ok so here's a few of mine.
I have issues with remembering to look for traffic when I'm walking with other people. Ever since I was young my friends would get very worried and grab my arm when we came up to a road crossing. "You never look where you're going!" I remember when I was younger being indignant, sure that I was just as aware as they were. It was so bad then I didn't even know I was unaware.

I still do it now but at least I realize it, if only after the fact. Good thing I have my husband to look out for me.

Normally when we go on a walk I don't remember any of it, just the great conversation. Walking seems like a really good way of triggering our Ne.
Another thing, which I'm sure is common to many of you, is I can
never remember where the car is parked. Or even how we got there, where we're at, or how we got to the store door, etc. Just yesterday my husband and I were leaving some shops to walk back to the car, he took me past the car, off down the street a block or so completely away from the car parking spots, and stopped in front of a noodle house. I looked around, "We parked over here?" Then after getting some food we were talking about my seriously lacking observational skills on the walk back to the car. After a minute I asked, "So where did we park then?" He laughs and says that yes I definitely am not good at details. It takes me a few minutes, then I realize we are standing right in front of our car.

I'd follow him over a cliff, not necessarily from loyalty, but because I wouldn't even have noticed it was there!
Oh yea, another one that always cracks up his family (all sensors) is when we make the 6 hour drive (this is all on a rural road, no freeways here) to visit them and not only miss the obvious turn off, but don't even notice until we end up in some city an hour or so out of the way. All the sudden we look out, what the hell are we doing in a city?! Oh shit we did it again
