It’s convenient though. You get live traffic data, international radio in high quality, maps with background pictures, music and video streaming, the possibility to pre-heat or pre-cool the car while walking to it and a few other things.
Most of these are possible with the smartphone you've already got and using the car as a dumb display + sound system (via CarPlay or equivalent), with the advantage that the smartphone knows its place and the little amount of leverage it has on you compared to a car.
Or... you can just use your phone + Android Auto / CarPlay. You will achieve same effect without connecting your car to the internet. And I will rather sacrifice preheating / precooling if it means, that I will keep control over my car.
LMAO. My wife's Bolt has CarPlay and I can go in the app and pre-condition the climate inside the car. And CarPlay has many features Tesla does not offer.
