Maybe there would be pre-war development of armored cars and armored vehicles, several with caterpillar tracks instead of wheels and rubber tires for off-roading.
And these could be designed for more speed and maneuver around potential entrenchments to try to secure and sustain victories in the mobile phase, so their designs might be faster and lighter and less plodding than those developed and deployed in WWI. They end up a bit underprepared for and underprotected from the volume of dense artillery fire, entrenchments, barbed wire, so revisions to design need to add more armor, heavier weaponry, more weight, trench and obstacle crushing ability, which slows down their speeds as exploitation vehicles.
