The website of the town where the photos were taken shared the images and the witness wrote a few words there : Comuna San Pedro de Colalao | San Pedro de Colalao | Facebook (scroll down a little)
Witnesses (an old couple) gave their testimony in a local channel, in my opinion they sound genuine: Witness interviews
Better quality photos, It appears that they were indeed taken with the window down:
There is no mention of the exact location where they were taken, only the general area. Searching Google Maps I was able to find the exact location: RP311 – Google Maps
