Out of spec and bearded tesla guy have both released part 2 on youtube but it's not the last segment for either.
At the moment the Cybertruck is slightly ahead of the Silverado and the Rivian is not far behind. The F150 can't keep up.
The interesting part is the Tesla guys have been able to use all V3s and have been aggressively making short hops to maximize charge rates, but on the other side of San Antonio they will need to use 3 V2s in a row, plus they will likely need to use a couple more V2s before the race ends. We'll see how much that slows them down.
The Lightning will probably be 2 days behind
