What I don't understand is
What I don't understand is why they don't use the tesla solar panels on the top and put the recharger batteries on back and then when power gets low turn it on and charge it while you drive. I'm a truck driver I can drive over 860 miles and average 7 miles a gallon. With stops and stuff I can run 24 hrs before fueling. And I don't see drivers wanting to stop for an hr at a truck stop to charge or a charger being available when you get there. All your going to have are dead trucks on the side of the highway.
