Actually it wouldn’t be an advantage. It would be a huge sunk cost (and added weight bogging down performance and handling) for a feature that virtually never gets used.
Tesla increases distance ideally by increasing efficiency. Their cars consistently score the best/lowest Wh/mi for their weight, by doing things like designing their own heat pump instead of traditional AC and resistive heating.
Because EV production is virtually always constrained by battery production, the number of cars you can sell is typically your battery production capacity (MWh) divided by your battery capacity per vehicle.
Their inherent efficiency combined with the Supercharger network to support longer trips lets them produce more cars at a lower cost / price.
