Barcelona has removed bus line 116 (which goes to the beautiful Parc Güell) from Google and Apple maps, to discourage the tourists from using it to get to the park.

This seems perverse to me. Do they want the tourists not to visit Parc Güell? To take taxis to get there? To travel by a more circuitous route? To walk a long distance?

If lots of people use line 116, the sensible and helpful thing to do is to run more frequent buses on part or all of that line.
