The 400 mile range is great, but I'm going to use a typical winter work day for me as an example.
I leave home at about 5:40 in the dark. Many times it is either raining or wet snow. So I need headlights, wipers and heater. I then drive about 70km on a twin highway to work. The truck will then sit for about 10-1\2hrs with out the benefit of being plugged in, since there is no plugs available, for any vehicles. I then drive home in the dark, also requiring heater, headlights and many times wipers.
My question is how do the additional loads affect the range? If I get left even once on the side of the highway, I would be done with EV's.
