This is exciting technology! My father in-law is a trucker, although nearly retired. He's fascinated by the developments made by you guys.
I'm not entirely familiar with the industry and day-to-day of a trucker, but I'd imagine you'd need some "on the ground" personnel, at least initially, to perform tasks such as fueling on long hauls.
Aside from this, it'd be interesting to see how quickly you can go coast-to-coast without a human needing a break/sleep.
