Rain sensing windshield wiper parts in parts catalog

Looks like GM parts sellers on the web offer Bolt windshields and wiper switches with rain sensing:

Seems odd that these parts would be listed when rain sensing windshield wipers are not optional or standard equipment.

It’s a feature in the Volt. Not Bolt.

Probably a typo.
