You also don’t discharge below some amount that I forget. Plus you want some buffer in case you have an emergency (if you go in the ditch a mile from home on that coldest day you better have enough power to keep the heater running until the rescue arrives)
40 miles is what I said, which might give you the typical commute - but it doesn’t leave room for anything else. Lunch errands, after work bowling league, emergencies and so on happen often enough that you really want some buffer and so the 100 mile claimed range is realistically marginal despite only needing less than 40 on the typical day.
There are many who are pushing rust as a religion tan that turns people off.
