  • except that manufacturers account for that and calibrate such that what you think are 0 and 100% are actually closer to 20 and 80% respectively.

    It’s actually the other way around. A safe cutoff voltage to prevent battery degradation is about 4.2V, but most modern phones charge until 4.45V, so they can advertise a bigger battery capacity at the cost of long term battery health. Your phone essentially charges itself to more than 100%











  • It seems unlikely that we will have fully self-driving cars soon

    Maybe not from Tesla, but Mercedes already sells 2 cars which have limited Level 3 self driving functionality. Up to 50 mph you are legally allowed to divert your attention from the road and do something else, you just need to be ready to take back control within 10 seconds of the car telling you to do so. Mercedes is so confident in that system that they are taking legal liability for any crashes caused while the car is in self driving mode. And Mercedes is already planning to get the car certified for speeds up to 75mph soon, so it will be usable at regular highway speeds
