Hi there :)

thank you for checking the iD validator for "wrong" mapping.

There are some issues with this changeset though:

- first up: it's not nice to map on two continents in one CS [1]. Please make sure to save your changes before moving to the next place.

- more importantly: Please don't just click on the fix iD proposes. Every time iD sees an "error" it's important to evaluate the situation carefully. In many places your edit has made the situation worse than it was before. 
https://www.openstreetmap.org/way/281271757 had "area=yes" before. Why would you remove that tag?

Many of the highways in Mexico you touched were flagged because of crappy mapping by others. Now you decided you give them a layer tag that most certainly is wrong in reality. We need to fix the crappy mapping first and that's sadly way more work than simply clicking "fix it" in iD. We need to contact the original culprits (some of them seem to be paid mappers from amazon) and talk to them.
Find street level imagery (NOT google) to confirm reality.

Please do not "run around" fixing things the editor found without really fixing things. Thank you.

safe travels
