Don't try it at home...but definitely try it wherever you are traveling! I have a whole collection of these kind of abstract shots...taken from the car window...while someone else is driving!
As an experiment, and to cure the boredom of sitting in a car for hours, I matched my shutter speed with the speed we were traveling...set it on manual focus, kind of in the middle of the scene somewhere! I love it!
But really, try it...and see what you come up with!
