The draw to keep an EV battery heated isn't that much more, and if you have 5 minutes or more lead time it will probably get up to the temperature you want by the time you get in your car. While it takes a bit to get used to turn on the car and then get ready to go, the real world experience is actually much nicer. Just make sure that if you parked outside that you watch for ice from the car having defrosted the windshield and the water going to the ground and freezing.
My experience is that a little bit of extra setup planning and you get a much nicer experience and an annoying experience if you aren't willing to think about your setup when you first get the vehicle.
According to all the latest reports, there was no truth in any of the earlier reports.
