People are incorrectly focused on a full charge at charging stations, but EVs really only need a full charge on the interstate and at home. With the Gen III having a smaller battery pack and less range urban superchargers might be necessary. First off, by urban I am talking about LA or Dallas, not NYC or SF. So how does one make superchargers useful in an urban setting? Gas stations work because they have a high turnover rate, so drivers are only at a pump for a matter of minutes to fill up and get a drink and then leave for the next car. But a Tesla takes too long to charge...but that is only for a FULL charge. So let's assume 150 kW superchargers will be available in a few years--within metro areas superchargers could be limited to providing only 15 kWh or 6 minutes of electricity per car. So 15 kWh will provide 33% more charge for the Gen III which should be more than enough to get home. These superchargers could be at normal gas stations around cities and suburbs. The key is that EVs can be filled up at home whereas ICEs can only be filled up at gas stations, so EVs will be able to get a full charge once they get home.
