Don't really see this as a "heavy cargo hauler."
This. I think of the vehicles I see driving around dense urban areas -- think NYC or Chicago, or any number of cities overseas (London, Frankfurt, Berlin, Paris). They need small, nimble light haulers and delivery vehicles. Adapt it into a small panel van, and it's delivering bread, flowers, restaurant supplies, etc. all over town. For cheap (electric, not gas), following local regs and not adding to emissions, and has plenty of range for the day's work (those vehicles drive 50 miles a day, not 150).
Definitely a similar function. But you get the EV advantage (fuel savings) and the upside of a new, warrantied vehicle with a lot less stuff that can go wrong (EV maintenance is cheap and super-easy). If I was running a restaurant supply delivery business in NY, or hell, even a pool cleaning business in Austin, I'd consider a bare-bones, low-maintenance, low-cost-to-operate vehicle like this.
But . . . that's a niche space. Hard to see Joe Commuter buying one of these as his daily driver unless he also needs the utility of what that package offers.
