Mr. Windshield was a character that was originally going to appear in Cars, but was scrapped from the storyline around 2003. Based on concept art, he was going to be a yellow Packard Clipper, although a 2000 concept sketch by Dave Deal shows him as a Packard Super Eight rather than a Clipper.

As his name implies, he was going to be a optometrist/windshield salesman, and while the character was scrapped, his shop still made it into the final film. Its design was reused for Ramone's House of Body Art.
