My name is Santosh, and I’m a mapper in the OSM team at Lyft. 
Thank you for your message, and for catching this error! The lanes tags shouldn’t be modified here. I apologized for this mistake. I have reverted my edits in the changeset:https://www.openstreetmap.org/changeset/172305783
I will exercise greater diligence when submitting changesets.

Best regards,
Santosh
