People will spot anything
. There's no accounting for taste.
I know one group of bus-spotter types who weren't happy with their local bus company, and started their own; "classic" (ancient, unreliable) buses staffed mostly by unpaid volunteers.
Even more so with trains - there's a restored steam railway near where I used to live, running a regular timetable... old diesel and steam trains, maintained & staffed by enthusiast spotter-types.
I'm just grateful that we haven't got many airlines like that
