I find a perplexing when you wake up in the morning and there's someone parked diagonal from you

I went to bed last night around like 11:30 almost 12a.m. and there wasn't a soul around me. I get up at 5:00 this morning, I look out the window and there's a car parked diagonal for me. Makes me wonder where the heck did they come from and how much pain did they put themselves in looking for a camping spot? My thought is if it's late enough you can probably get away with just parking pretty much anywhere off the beaten path and just get up early and move on. I've made it a thing to really not do that kind of stuff anymore. I like to find my camp by 3:00 in the afternoon. (I'm currently at an ioverlander site)
