Obviously the truck is moving.  Your brain perceives motion that doesn't
really exist.  A really good example is watching a movie.  Yes, the film is
moving but it contains several still images that your brain puts together
and perceives as motion.

Stick with eyes since you obviously paid no attention in physics
class.  My proof that motion does exist.  Go stand in the street and
tell me what that truck is doing.  If it isn't in motion, then it
won't hit you right?  Physics 099, Logic 101, Intensive care 1000

motion doesn't exist......that's a really good one doc.
