Yeah, you pretty much have to do that with any EV. You don't want to frequently charge over 90% to preserve the integrity of the battery. Same with the bottom 10%. You don't want to frequently drive the car down to 1%. I think it's not a huge deal if you drive it down to 5% or so, but as an owner of an EV, it gets pretty scary to go below 10% before you charge if you're on a trip. If the wind speed/ temp/etc gets out of control, it can sap your battery before you make it to the next station. Ignoring 20% of the battery is pretty much the standard on today's EVs.
