If legacy US auto and Tesla choose to not make cheap EVs, allow China to sell into the market (with strong right to repair and consumer protections around anything where these products could be used in an adversarial way, telemetry, data security, cloud dependency optional, etc). If these builders start delivering cost parity vehicles, implement tariffs accordingly to defend the domestic market from dumping (very common).
Worst case, we send all the battery packs off for shucking to use in stationary storage, or recycling by Redwood Materials. That’s US refined battery feedstock ore now. Regardless, we’ve got lots of combustion miles to replace with EV miles. We must move faster.
