In the 300 mile range you start to get near the point where the average (mean and median, maybe not mode) commuter can charge once a week on an average work week at a fast charger at the local grocery store for merely an hour or two and still not worry about range. Work charging and home charging are nice to have slow and steady options that make EVs
easier than gas, but it's about to the point where if you treat it like "gas" with a once a week fill-up that is increasingly an option if you relax your worries about "range" to the point that gas users are currently relaxed about in keeping their tanks full.
(Range anxiety for ICE will eventually make a huge comeback. Electricity is everywhere, imagine driving a car where you couldn't just plug in anywhere the electric grid is and had to go to "stations" of a scarce mostly single-purpose resource for power. Haha.)
