NSCAR pit stops with possible battery swaps maybe in racing's future not mine. I haven't watched an Indy race since the rear engine cars took over. I just don't care. Electric cars are taking over, The Nevada Tesla Gigafactory is directly over the mountain from me, probably less than 10 miles. They are enlarging the battery plant & opening a truck plant (500 mile range tractor trailer rigs) That will give the drivers time to sleep while charging unless a charged truck is waiting. It is OK they will drive themselves.
It is becoming apparent why the Government (BLM & USFS) is closing roads on our public land. There is no way to have charging stations way out there. I've been living "off the grid" for 50 years. I have a mill, lathe, welder, belt sander, compressor, microwave....., but I'll never have enough power to charge an electric car.
