I was trying to look for that kw/h reading for the trip but I could not figure out how to get it for the whole trip, it only appears to show last 10km, last 25km or last 50km, but not the whole thing. The last 50km came up as 124 Wh/km and strangely when changing from % to range, it suggested the remaining 10% would be 50km range remaining, which did not make sense as it used 90% of battery to do 320km, so in my opinion the 10% should be just over 32km. When the car was at 100% charge, then changing it to display distance showed range of 390km which now afterward appears a bit optimistic also.
I really hope they will start putting charge options in the larger petrol stations spots along highway, as I had to stop in 2 of those on the way anyways to get coffee and donuts and let some passengers to use restrooms, would have been awesome to get 15-20 minutes charge top-up during those stops
