From what I see from comments in this thread, these trucks are meant for pretty specific short haul use cases, with consistent routes and perhaps the origin and destination points being owned by the same company as the truck (eg Pepsi, FedEx)
So for example, if this truck carries packages between two FedEx facilities in the NYC area, its chances of encountering a cash-only toll booth are zero, and the company can use electronic records systems that obviate the need to present paperwork (in fact, I bet FedEx does this already anyway.)
Likewise I believe many if not all weigh stations in this area are electronic as well.
So it may seem superficially that Tesla traded off one thing (driver comfort, by forcing them to get out of the cab more often) for another (energy efficiency due to aerodynamic design) but in reality it maybe that in these use cases, the driver won't be getting out of the cab anyway for reasons above, so it's basically "free mileage."
I can make similar guesses as to why some of the other complaints don't actually hurt anything, or maybe are worth it. Eg: let's say there are 3 times a year the driver has to get out of the cab to clean the mirrors. Maybe doing that 3x a year is well worth the increased energy efficiency of every single mile this truck drives in it's life.
