In no specific order, just off the top of my head:
1.) Maximum Overdrive.
2.) Mad Max: Fury Road (an obvious one).
3.) The whole Kitt vs Karr thing from the Knight Rider series.
4.) T-34
5.) and that scene from Raiders of the Lost Ark when Indy takes control of the rig holding the ark and starts plowing through everyone in it.
I just saw a really bad movie version of a good book called Wandering Earth. While the movie was horrible, they had some great giant trucks, and some even had strafing ability. All the wheels could pivot completely, which allowed them to stop suddenly and go sideways.
I could go for a Train simulator done in the style of Crossout, maybe for the range?
You could give it a crafting feature, where you contribute resources to it, then it drives off into a tunnel on your ranch, and then comes back later and drops off the part? Sort of like combining a farming simulator with model trains.
You could build different styles of cars that delivered different kinds of loads, like a flat bed rail car that you donate resources to, then it when it returned it would deliver a cool new blue print, set up and ready to go.
The developers could use it to deliver seasonal gifts, upcoming event advertisements, or resources too, like they do with the visitor feature.
Ravager trains? It’s be great for Adventure Mode too, I think.
