Why instruct some to turn towards bad weather, because it had gotten so bad?
The man in the tower can see only the bit of wx around the tower. He cannot know what the pilot sees once the pilot is some tens of seconds, never mind minutes, down the road.
Pace - your example of Spain is very good; the worst ever ATC service I have ever had was in Spain this year. And arrogance over PPR issues rivalling Italy. I think pilots flying into these places really need to grab the bull (no pun intended) by the horns and be prepared to take on ATC if the instruction is unsafe. I had Spanish ATC ignore me when I requested a 30 right due to weather, and eventually I did a Pan and got on with it. You would have done the same. But all that is a world away from the UK PPL scene where all authority is taken as emanating straight from god.
