|Take roads. A Usable road is one that is wide and straight (less mental effort), with no oncoming traffic (less mistakes, less mental effort). One that enables you to get from A to B as fast as possible (more powerful) and one that has a consistent and clear use of signs (high learnability).|

|A road with a high level of user-experience is completely different. It is a twisting mountain road (visual). Now you got great scenery (visual, emotional), the smell of nature (smell), the excitement from the climb (and the sheer cliff only feet away).|
You got little friendly signs put out by the local, who sells fruits along your way (show-off effect). Every city is slightly different (branding, emotional, environment). You feel happy when you see the locals wave when you pass by, and you stop let a sheep pass (emotional, trust, coexistence).
But a mountain road is far from a usable road. It is much harder to drive on, it is difficult to learn, you can't go as fast and the risk of making a mistake (taking a wrong turn or crashing into a sheep) is much greater. But, a mountain road will give you a much better user-experience than any freeway could ever do.
