Just listened to the call.... here are some of my takeaways:
1. Zachary Kirkhorn needs to be on every conference call. No offense to Elon, but Zack was the superstar of this call.
2. Listen closely in the future for developments in Tesla Energy. It seems that Tesla Energy will be the focus of a dominant portion of Elon's time/energy for the near future.
3. Elon was probably very annoyed that autopilot uses brakes so much because of how inefficient it is compared to regen braking. Improvements in single-pedal driving/better regen braking are the result of this.
4. Faster supercharging for SR and SR+ is not only great for customers; it's a great business move. Getting people in/out of superchargers quicker means not having to build out superchargers quite as quick (or, on the opposite side of the coin, less complaints that superchargers are always full).
Funniest moment of the call: When asked about possible software revenue stream, Elon replying that cars from other companies have no soul.
