@kravietz also the flooded area seems to be on the same level as the bridge in the background, so there should be some lower area where the water should be going
@guenther And "Maserati".
I mean, everything on this photo is so fucked up that I can't believe it's not a PhotoShop :) However, photo forensics ELA doesn't indicate a manipulation...
