Yes exception for very cold weather when regen is limited. Not so much to do with road salting, just use of brake pads versus non use, although salt could help cause rust to disks, not pads, which could in turn affect pads. But yes certain conditions may vary.

This makes no sense. Reducing or turning off regen would make brake pad wear worse, not better. As an owner I assume you know your stuff so typo maybe?
