Definitely, we've experienced workers being sent home for a number of reasons (too cold, too windy, too rainy, materials didn't show up as scheduled). Fortunately with an autonomous system there's no logistical overhead, if some external factor prevents us from working then we aren't stuck covering hundreds of per diems and sending everyone home. Yes, we'll have some equipment depreciation as it's not working, but it's at a similar rate to the rented or depreciating trucks/skid steers/telehandlers on existing sites when no one's working them.

Totally hear you on the CA vs MA weather swings (I've lived in both!). We actually see this as a key advantage for us. Sites we've visited in central CA have significant water distribution logistics, frequent shade breaks, and still have high heat exhaustion rates. Sites we've visited in northern climates report about 50% speed reduction in work due to gloves/cold, and will send workers home if the temperatures drop far enough. Our robots can handle both climates without an impact on installation rates (or any of the associated health risks for workers!).
