It adds three simple sliders to your startup mod settings so you can change the speeds to whatever you want. I separated them into categories because flying units usually do not need as much of a speed boost as ground units trying to navigate factory spaghetti.

Ground Caravans: Affects normal caravans, fluidavans, and their turd versions.
Flying Caravans: Affects flyavans, fluidflyavans, and their turd versions.
Nukavan: Affects the heavy radioactive nukavan and its turd version.

It automatically updates every caravan currently walking around your factory floor. You will not have to pick up your existing caravans and replace them manually to see the speed boost. It also only scales the actual movement velocity, which means the running animations stay smooth and do not look glitched out.

It consumes absolutely zero UPS / runtime
