Would you be able to obtain information on how fast Dave Cloud drove for most of his highway driving?

191 Wh/mile would seem to be quite high consumption for a car as aerodynamic as that if he were only doing 55-60 mph! I understand that the car is heavy due to the battery weight, but even at speeds over 50 mph in a body streamlined as such, weight is nowhere near as significant of a factor in energy consumption. It may be possible that his tires are unsuited to maximum range, OTOH. If he has tires with a Crr ~0.01, then maybe that 191 Wh/mile figure would make sense. There are EVs nowhere near as aerodynamic as Dave Clouds EV that can get by on ~120 Wh/mile at 60 mph, even if they might be more streamlined and lighter in weight than the norm, but they are nowhere near as streamlined as that.
