You know that commercial where all the Ford vehicles are driving around on the ledges and sides of buildings, irrespective of gravity and general safe driving practices? Has anyone checked out the bottom of the screen for the disclaimer?
"Yes, this is a fantasy. Vehicles can't really drive on buildings."
Oh, come on, Ford. Don't be so modest. Vehicles can totally drive on buildings! They just, you know, can't drive on the sides of buildings. At least, not until you get that radioactive spider bite technology to interact with cars as well as it did with Peter Parker!
