"That which the large print giveth, the fine print taketh away." In this case however, the charging time details haven't altered my user experience in any way. Real-world charging stops really are in the 12-15 minute range for us.
I really like the colourful chart they have showing different charging speeds between different charge points. Thanks to that I think I'll probably try to charge 20-80% most of the time.
I'm used to thinking about it like a phone, which is always charged to 100%, but I think with the car I'd rather keep it to 60% or so for day to day driving around town and only take it to 80% or 100% for longer trips.
I'm going to try doing these measurements for my own car though, since the article was based on a prototype.
