The arguments in that discussion don't really make sense either. Such lanes exist outside Latin America too. Like the "busbaan" in Almere, Netherlands. Edit: And in Diemen, as pointed out above.

But generally this "process-first" attitude makes me step back as a contributor immediately. I prefer doing something the wrong way and fixing it later instead of not doing it at all.

The same thing totally antagonizes me against Wikipedia editors so I never participate there either.
