Again, this is a terrible example. I'd say that a good third of passengers are wondering exactly that. (It's irrational to do so, but that's another story.)
And further, skilled pilots can be recognised by their landings, particularly in making soft ones in stormy conditions. Perhaps also in their customer service with witty commentary over the PA.
Divergent, but any skill I can think of will have a distribution of abilities. Some of these skills have a threshold beyond which incremental improvement gives little benefit. Walking example: if you can walk 100m in one go, you are better off than someone who can walk 10m. Likewise, 1000m > 100m. Does 500km give any more benefit than 50km? Maybe, but probably only for extreme use-cases (maybe competitive extreme-distance walking? I'd rather drive!). Similarly with technique - if walking technique is horrible it matter for mobility and injury risk. Beyond a certain level, it probably matters less. And maybe walking extremely well is a visual-social signal, as a marker for someone who is in good shape? I'd read somewhere research done on dancing as a marker of fitness for attractiveness to the opposite sex.
