I have not planned a long trip yet where I would need to charge, although I am considering a trip to NC. This would be 520+ miles, which would be two charges needed, and even if I found DC fast chargers along the way (ie Savannah), the total time would be 10+ hours. I can find a fight for less than $80 and it takes 1.5 hrs. I am not so keen to take long driving trips as it is.
You are being very optimistic to say you could travel 520+ miles in 10 hours with 2 charging stops
