I've had two service items with my Tesla, and each left me very unsatisfied because I had very basic and quick questions that the app would not answer (e.g. how long is this expected to take?) but there was no way that I could talk to a human at Tesla. They have optimized their system to prevent any human to human contact unless it's in store.

However, as bad as that experience was, it was faaaaaaaar better than any dealership interaction I've every had. I would never go back, even though I disliked the Tesla experience.

Even if Tesla wasn't an electric car, I'd be tempted to use them just to avoid the dealership experience.
