Have you ever wondered why UFOs pilots seemed to be driving awkwardly?

70% of the UFO cases i've seen on videos are rather weird.Now whoever is driving these Crafts seemed like they either have no idea how to drive this thing,they are drunk,they're on drugs or they just love to go in unexpected directions.. Not that its wrong but its kinda weird to drive something up,down,left,right and suddenly vanishes off.

These guys need driving lessons sheesh..

Perhaps that's just how it appears to us in our frame of reference. If these things can cancel inertia, bend space-time and such maybe it's just the way the tech look in operation.
