If you do, you are wasting your time and the time of anytime else waiting for that charger. I’m currently sitting waiting at a DC Fast charger for 30 minutes because some guy in an ID.4 has decided to charge to 100%.
It is nearly always better to charge to 70% or 80% and stop more often. Stop fucking it up for everyone. If you don’t know, the charge rate slows down dramatically the higher the state of charge. I could have charged from 20-80 in the time this guy went from 80-100

Well, is the driver actually waiting in the car for it to hit 80% or are they out actually doing something like having a meal / shopping? If latter, they are certainly not wasting their own time.
