Yeah, I know most of you are ready for the summer related stuff now. However, here at 70 degrees north of the Earth's equatorial plane, the Winter is strong, and we still have 3 feet snow at sea level. After driving Model X one winter in hash conditions, I find a simple function still missing: Range Mode without reduced heating capacity. Let us have the opportunity to not use the battery warmer, but still have enough heating capacity inside the car. Tesla engineers, if you are reading: Please, let us have a button named "Battery Heater OFF". Or an option for Range Mode named that gives full capacity for heating inside the car. This will increase range and decrease power consumption a lot for shorter trips in winter, and still let us have maximum comfort. Should be simple to implement. (Off course, will not affect temperature levels for battery protection) This is #1 on my wish list, and will strengthen Tesla's position as a winter car and an energy efficient car.
