This is very true. Take the FedEx logo on the side of their aircraft and everywhere. Most see it initially as five letters. Only when somebody points out that the space between the orange E and the X forms a (deliberate) right pointing arrow do you see this, and thereafter whenever you see the logo it is difficult to not do so. To those who have "seen it" then it is "obvious". Not to others. And once you have seen the lights of the right-hand strip, that is what your brain is going for. Goodness, people have quite regularly lined up on and landed at the wrong nearby airport, let alone taxyway.
