"Typically, if you trickle-charge every night, then an average daily commute would still leave you with 80%+ charge."
You keep talking about this "average daily commute". Few people do that. There are large numbers of city dwellers who drive as little as 1-2 miles each way, skewing the average right down to an "average" of 10 miles per day (each way). But you are ignoring the similarly large numbers who do a more than 10 miles (each way) and especially those significant numbers who do 50+ miles each way every day. I can't find the link now, but a Gov report from about 2015 or so showed the graph and it was not a bell curve. It was more like a side view of a saucer (sans cup of tea)
Having said that, the same report did show that the numbers of people commuting had reduced a little over the previous 10 years and the fewer people were commuting for a full 5 day week. But that was 4 years ago. Things may have changed, trends could be continuing or reversing now.
