That's the charge LIMIT not the charge the battery likes to be at.
The service manual that states 15-50% is specifically for the Cybertruck. It's in a PDF document that was posted on this forum.
What's the difference? The battery degrades whether you are using it or not. Using it makes it degrade more not less, so in storage it is more resilient and you should be able to keep at a higher SOC not lower.
Yes a quick glance requires it to be even clearer and brighter. If I had all day to look at it and figure out what Im looking at then maybe a blurry and dark picture would be OK.
v11 always drove in the center of the lane and never drove 30mph below the speed limit or flow of traffic. That's already two giant steps backward on a newer major version.
Every release is a step backward. One step forward, two steps back, net result is one step backward.
Occasionally you will get a leap forward, like v12.5, but then it's back to going backward. Net result is FSD just treading water and going nowhere.
