Everyone's experience is different. I find the Tesla planner only useful for short trips, less than 300miles. It's improved over the years, with waypoints, etc., but I haven't found it more accurate than ABRP, which is highly accurate when you subscribe and it uses wind data, etc.
Just look at your example. The Tesla planner shows 12h driving and 3h charging, for a 15h trip. Google Maps shows 11h22m for driving. The two are not even driving the same speed. If you stick 5mph over the speed limit in ABRP or 8% over, then you get a driving time of 11h26m. That's more reasonable for comparison.
The Tesla planner's charging times are all rounded to 5min increments. Plus, it estimates 3hrs of charging. Is that at all accurate for 800 miles of driving? Let's say you're using V2 chargers and getting mostly 500miles added per hour. 3hrs of that would give you 1500miles of charge. Way overshooting the amount of charging time.
I'm just saying that arguing the Tesla is not as good as an ICE for roadtripping, and then using the Tesla planner as the example, is not really a fair comparison.
