Do drive the car normally and don't sacrifice comfort, but remember that many of the things people do to extend range will also save energy and reduce your cost of operation. So use the seat heaters when it is cold so you can set the HVAC temperature lower and still be comfortable. Lower the fan speed a bit from what auto mode selects. Use the charge timer so your car only warms the battery just before you need to use it and not all the time. Set the charge target to 90% or less even after the battery gets replaced so you always have full regen available.
