I admit I never had a service need that prevented me from driving: I have a preemptive A/C tube replacement and I have an appointment to replace a tire pressure monitor, so I can't attest to the quality of service. Regarding autopilot, I agree that it's bad. I don't know how it compares to other cars - I've never driven another car with lane-keeping - only a Toyota and a Volkwagon with adaptive cruise control, and my Tesla seems to be as good as they were. In truth I think the whole "self-driving car" idea is a horrible mess. If I were a regulator the only self driving I would approve is Level 5 - full self driving, and maybe level 4 which is really level 5 just geofenced. Either you're driving the car or the car is driving itself, you can't have it both ways. Adaptive cruise control is still you driving - because if you lose focus or attention for more than a second or two you'll slip off lane - while lane keeping is horrifying to me because you could lose attention for half and hour and still be fine - right until you're not (and neither is the person you hit). All this to say that yes, Tesla's autopilot is crap, but I don't use it and wouldn't use a competitor's version, so I don't measure it by that yardstick.
