I think Bjorn tested a Leaf 40 in Norway when it was cooler and it was still basically useless. I had one and it was nearly in the red from 2 short rapid charges and driving at 70 mph. There was gaps in between so not constant charge and drive too. Never had any EV be so frankly crap at it. Used to charge a much older Kia Soul EV multiple times and it didn't care at all.
