I pulled some video of the digging equipment I had seen stored in the deep excavation under the Pre–Corporation Rim colony structure when the Targets had stuck me down there to get contaminated. I had been more occupied with leaving than with taking archival footage of aging construction equipment, but while there had been some wheeled vehicles, most had been the kind that can float a little distance above the ground. Which made sense in a developing colony where you would need to build your infrastructure as you went along. But it would also use a lot of power. There were more efficient ways to move those vehicles.
