"Don´t invoke local communities."

Why?

"Do the Chilean mappers have a say in this?"

Of course! Please feel free to comment, and as someone who has been watching the region for a long time, I'm taking your point of view into consideration, even if I disagree. For me, your opinion counts, adding to those on the tagging mailing list. Together, they all currently lean towards your version. If within a few days the consensus continues to indicate that, I will update the wiki and downgrade highway classification in all of Antarctica uniformly to reflect the consensus.

"Did you discuss with the Chinese and Uruguayans?"

There are very few mappers in Antarctica, so I haven't found any yet other than casual mappers uninterested in highway classification. In fact, over two years, you are the first Chilean mappers I have come across in Antarctica. I've seen mainly Europeans from various countries. The initial mappers of the Fildes Peninsula no longer appear to participate in OSM.

"this is another "I own the place""

Quite the opposite. You can check the history of highway classifications in Antarctica in multiple places, not just the Fildes Peninsula. When I started, there were big discrepancies between these places: what you just changed to tertiary was similar to another road somewhere else that was mapped as service, somewhere else as track, somewhere else as residential, somewhere else as highway=road, etc. I welcome suggestions on how to improve the result. I don't think different parts of Antarctica should follow different rules, but the rules are up for debate, and as far as I know, this is the first time the are being debated specifically for Antarctica, which is a unique place in the world.
