The standard for what can be lawfully seen is not written assuming the view of a 6' tall male. A person can lay down on the sidewalk, an area he can freely occupy, and gain a whole new vision of a person's property, including under a vehicle.
I can lay down on a sidewalk so as to achieve a better viewing angle through someone's window to see a poster on a ceiling inside of a house and still not fail the cases that I cited.
As I said in my other posts, I don't agree with the law, but that is the law.
