Also, Gray Catbird, on The World of Cars Wiki, the page about "Mama Luigi" shows a picture of Luigi waving goodbye to her on a ship, which doesn't seem to have the mouth on the bow. And steam trains may have two separated windshields/windscreens, which the vehicles in the Cars world usually have their eyes together (except for Celine Dephare, who has her eyes in her headlights), so I don't know. Also, if you look closely at the "pet steam trains" in the Cars 2 State Farm commercial, you may see that the eyes are on the front of the steam motor. So proper steam trains might have their eyes on the front of the steam motor (and as I said, I hope Cars 3 reveals that the proper versions of animals also exist in the Cars world).
