Yeah. I think you’re missing the point. The heat pump provides a massive gain in driving efficiency. I’m not going to go through the laundry list of other changes.my heater works fine. What other features? Must be ones I never would use. There are quite a few things the car offers that I do not use. Personal driving choices for what works for me.
So your statement, that there are no changes between a 2019 and current Model 3 is just beyond false and misleading.
