As for me, after four Teslas and a couple hundred thousand miles on them I wonder what "service" we're talking about. Personally I just adjust my own windshield wiper blades, so I don't need to go to the dealer. Maybe you folk are so used to taking your gas cars in for "service" that you just keep taking in your Teslas. Beats me.
Why is it that in so many places on social media, one person's experience must invalidate another? You haven't had to bring your car in for service? FANTASTIC, good for you. But please, don't project that experience on everyone. All it takes is reading through these forums for 10 minutes to realize that there are enough things going wrong that people have to interact with Tesla service all the time.
