Luna is fine until the second she sees MC at which point she immediately wants to bail and keep her daughter away from MC, sure she could know and (off screen tell skylar there is time travel) but its more likely that it has to do with her "weirdness" that she mentions in the cafe when talking with MC, so there is one potential person, another is Valire and the only assumption required is "she remembers MC and isnt just a horny older lady"
Unless the story has a (already controversial) LI be told something that "any logical person" would think is not possible, then have her believe her mom and lie (both directly and lie by omission) to MC about it would be a very odd choice, even moreso when Jestur repeatedly said just trust the story etc (when she was lying about her tattoos). People gave up on her both when she got a random "redesign", and when she lied right after. To stack a third lie on top of that (without any resolution) is not going to sell people on her.
We know that the bad guy organization is not very competent for a group that is (2nd closest?) to time travel. Someone clearly high up (on the science side) is talking about how he prefers to rape living girls, while the underlings prefer necrophilia, Riley is able to sneak up and beat one of them with a baseball bat, MC is allowed to walk to the time machine whenever he wants despite it being on their land, as to the 4k cameras.....uhhh where? from the people literally hiding in bushes as cover? Did they replace all the grainy security cams you'd expect to find around a small town in 2019 (assuming they were brand new when the game released).
All of this speculation (while fun) is pointless because Jestur (who we both agree is very detail oriented) shows the truck being at EVERY LOCATION (parked) before MC/Darci get there (see below) as to why he didnt change the color or make any other edit? considering nobody noticed (cheked thread for truck) for the entire time between updates it would have been minutes/hours of pointless work, and this is coming from someone who tracked down a picture of an irl location that an in game newspaper clipping in the background mentions in pale carnations
