For me in AU with the M3P range is most definitely an issue. Non-tesla DC charging is some 200miles apart, which in our case means we're using a flaky 45kW charger half way to make it to the first SC. Theres only seven SCs in the state and its the size of western Europe or 4x that of Texas. In our case even just an extra 50miles would knock off 20minutes on our trip.Real world means a "400 mile" pack doesn't give you 400 miles so it's not a 6 hour trip, more like 5, and yes I can usually do 5 hours without stopping and I'd like it to be my choice not the vehicle's. Following your logic there is no need for more than maybe a 150 mile range pack to avoid plugging in for a few minutes at a time. You also ignore the fact that a larger pack will be running at a lower C rate for the same power level and will last longer.
During long distance highway travel, when range actually matters, weight has a far lower impact than aerodynamics, plus the extra capacity would only add the weight of about one additional passenger. You notice a range difference when you carry a passenger? I don't. You also ignore the continued improvement in battery energy density which means extra capacity without weight penalty.
In our driving conditions, with rough spray on bitumen roads (high rolling resistance), windy and over 110F in summer, its hard to use under 200Wh/km at 80Mph even when "hypermiling" it. Going slower makes a 5 hour trip 6 or more. We don't have any city driving around us where you drive slow enough to make EPA range, here its open country and every electron is needed to move air and mass. So give some more kWh!
