Eh, I watched that one yesterday and it's a little creepy, but it doesn't bother me much at all knowing the Prague alternate opening scene from Cars 2 exists.
While we're on Cars 1, here's one I really don't like.

The characters being able to move from one body to another is just weird and I really do not like the idea of McQueen being a steamroller. However, my biggest problem with this scene is Mater's portrayal. I don't like how he's portrayed here because he just seems like such a jerk and comes off more like a villain in the movie rather than a close friend to McQueen, all of which just seems too far out of character for him. While I'm aware this scene is just a nightmare McQueen is having and nothing more, but Mater driving off in McQueen's body and leaving McQueen as a steamroller to fix the road is just too much dramatic irony for me. I know McQueen was quite a jerk in Cars 1, and maybe it's been too long since I have watched it again, but I actually feel bad for him in this scene, even if it's just a dream. It kind of gives me vibes from the "Wrong Buzz" and "Woodie's Nightmare" scenes in Toy Story 2, and while they're not deleted scenes, I am not fond of either one.
In the end, I just don't like this scene for the reasons stated above and since most of it is only a dream, it's kind of pointless anyway, so I am really glad this was cut from the movie. What we got in the final is so much better.
