I notice it in our local swimming pool where people swim endlessly from end to end, some will take common sense or courteous avoiding action whilst others stubbornly carry on, refusing to deviate from their chosen course,  leaving it to others to keep clear. Similarly I see boat owners of both persuasion doing precisely the same thing, but why? What is so hard about moving either tiller or wheel and why do some folk get so visibly angry about having to? 

Its exactly the same when you walk round morrisons!
