Most industrial facilities already have 3-phase 240 or 480 power and tend to be fed by higher capacity feeders than you see in residential areas. They also tend to be closer to high voltage feeders because everyone hates HV lines running through residential areas.

People are way over-estimating how much work will be needed and how difficult it will be. In many cases the utility will either swap out or drop another 3-phase transformer in place with CT-based metering. The customer will run some conduit. The more power you anticipate purchasing from the utility the bigger the discount they'll give you on the work. In some cases the existing medium voltage lines will be at capacity so they'll pull a new one from a substation but they aren't going to charge $1m for it. This isn't exactly rocket science... everyone who builds a new factory goes through the same process. Utilities do this work every single day.

EV truck fleets will be rolled out over time. The grid and charging infrastructure will adapt. Everything will be fine.
