Oooh, I wonder how long this car has been there and if they were skeletal yet. I have been tempted to run either a high res satellite scan or regular drone scans along those roads just to find cars like this.. you could probably solve a bunch of missing persons cases every year if you had a regular enough survey (and perhaps might even find people in time for survival if it were a weekly thing).
