Think of any construction that's remote though. Especially infrastructure. Wouldn't it be cool if a bunch of excavators could just work all day and night to dig that trench, move that huge amount of dirt from one place to another? I feel like there are lots of situations where automation could be done.

At the scale where automated earth moving equipment makes economic sense, those restrictions often won’t apply. Highway construction and other vertically integrated projects are where this potentially makes sense.

Operating hours are the least of logistical hurdles for most projects. Schedule coordination dominates and the critical path can only move as fast as the slowest element on it.
