No one has mentioned the diff between v2 and v3 Supercharging. Since your latest recommended trip involves stopping at Bakersfield which is an old v2 style charger there is something to know about them.
As you approach the chargers you will notice that it each station is numbered, 1A 1B 2A 2B etc...
The numbered stations are paired A & B, so if you go to charge at a numbered station and someone is already there or someone arrives and tries to use your same number than each of you will get HALF the power. That doesn't quite mean it will take twice as long to charge as above a certain threshold your cars stop drawing full power. So if you pull up and see someone is already on the numbered charger you are aiming for, look elsewhere. If someone pulls in and heads for the same numbered charger as you politely inform them it would be faster for you both if they looked elsewhere.
DON'T get fooled by those rare Superchargers that have the stations numbered 1A 2A 3A 4A 1B 2B 3B 4B where you have to walk down the line to find which station you are paired with.
If half of the chargers are ALREADY taken you are going to have to pair with another car. In the old days the first car got the majority of the power and as their car drew less the other car got more. There must have been a lot of complaints as now I keep seeing the two chargers get split in half, so the 150kW is split into two 75kW stations (Like Urban Superchargers are the whole time, if you are unaware someone else can explain the Urban ones).
So if you are heading to a v2 Supercharger and you see that half or more of the chargers are in use it may be faster to go to another charger. Button Willow is like the next exit northbound, so that might be an option. Also the new Bakersfield charger that JUST opened is v3 so everyone gets full power all the time and you might hit up that one, but it's a might further south and that may change your trip planning, perhaps not being able to reach Firebaugh you'll get directed to Harris Ranch and then since you are further south again you may need to stop at Gustine to make it all the way home.
Personally I like to run the car way down before stopping so I am drawing full power the whole time, so I'll pull off the freeway, plug in, go pee, and come back and unplug and hit the road again. I could spend 24 minutes filling the car at Kettleman or spend 5 min at Button Willow and 5 min at Gustine. Sure they are v2 chargers but they'll charge pretty fast if I get my own station which is likely now that people prefer v3 stations. The downside is that you end up passing the SAME cars and trucks you did on the previous two legs...
Five minutes MAY be an exaggeration, depends on temps and winds, just trust the NAV system to get you there. Eventually you can trust your intuition, but the more conservative Tesla NAV will rarely leave you high and dry.
