Mike has LiDAR-scanned cart ruts at sites he has travelled to worldwide and sent the scans to Sean Harrison, who compiled them into a big analytics database plus a website with interactive tools and 3D models. The argument made in the video is that rut measurements usually credited to the Romans show a continuous lineage older than Rome — so Rome inherited the unit of measurement. They also argue the ruts could not be wheel-made but came from sledding, and are always paired with wedge-cut practice. Compare them with modern wheel tracks at Round Rock, Texas, which look like real cart ruts and are far shallower 🛞📐
Video claims cart-rut measurements predate Rome and that ruts were made by sleds

Key facts
- Mike has LiDAR-scanned cart ruts at sites he has travelled to worldwide and sent the scans to Sean Harrison (28:11-28:25)
- Sean Harrison compiled the scan data into a large database of analytics and built a website with interactive components and 3D models of the ruts (28:23-28:56)
- The video argues that cart and rut measurements commonly attributed to the Romans show a continuous lineage that predates Rome, so Rome inherited its unit of measurement from an earlier civilisation (28:59-29:22)
- The video argues the ruts could not have been produced by wheels and instead result from a sled system, and that they are consistently found tied to a wedge-cutting practice at the sites where they occur (30:23-30:53)
- The Austin-area ruts are contrasted with modern wheel cart ruts at Round Rock, Texas, which the presenters say look like genuine cart tracks and are far shallower (31:01-31:22)
