The biggest reason, efficiency. Heat pumps are 3 times more efficient than a resistance heater! Quite impressive to say the least and will definitely allow people in colder climates to get the most range out of their battery as possible while staying comfortable inside the cabin. Watch the video from DÆrik for more info:
A heat pump is a device that transfers heat energy from a source of heat to what is called a thermal reservoir. Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one.

A heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink.Electricity is used by a compressor to send refrigerant around the system and capture the heat outside before bringing it inside./wikipedia
