A drop from 80% to 20% in a 300mi car is 0.6 * 300 = 180 miles. It's a 350 mile trip. 350 / 180 = 2 80-to-20 discharges, and that's assuming no little detours for stopping at a cheese store or whatever. So we could do it in 2 stops if we were OK arriving with 20%, but we need some charge at the destination for getting around MKE, so it's three stops. And yeah, we drive 75 because that's the speed of traffic and the HVAC does whatever it does to make us comfortable.
