Am I missing the advantage(s) of the Twin Chargers option? I don't see any:
20KW means something like 90amp delivery, which means over 100amp circuit breaker. You're not going to find those on the road, so it's only for home, where you've probably got enough time to charge at the usual 40/45 amps.
For Supercharging, we apparently don't need the Twin Chargers, just the 85kWh battery. That's what we'd target for long road trips.
So, why get the Twin Chargers? This is reason alone for me to not upgrade to a Signature model (don't want to pay for options I won't ever use).
