Sometimes you want to disappear. But often it is better to avoid what people are looking for, or at least, obscure your direction and intentions. It is a very old problem.
The problem in WW1 was U-boats. The solution was dazzle camouflage. Even though the military was never quite comfortable with it, contemplate the second illustration while maintaining a straight face and a military frame of mind, it worked. Dazzle painted ships suffered fewer losses from submarines.

You don't need to paint your vehicle in a dazzle color scheme to obscure your presence and intention. A plain white pickup truck with a generic magnetic sign on the side telling people you work for "Universal Logistic and Consulting" will get you a lot of places. Step out with a hardhat, clipboard and day-glow vest and you disappear into the background. They see you but really don't.
How many other ways can you think of to hide in plain sight?
