I didn't really believe this back when I was driving a BMW and Honda daily running CarPlay, but now that I'm on the Model 3 I'm hitting lots of software bugs on the Tesla head unit that would've never passed even the most basic of software QA at my previous job.
The Tesla head unit makes the current automaker's head units look super reliable and as solid as a rock. OTA software updates do have their benefits, but it seems like it leads to compromising quality for pushing features of questionable utility out the door.
I get really disappointed when I see Tesla implementing really unnecessary features like Rainbow Road (the over-done SNL "more cowbell" skit) and fart mode. Focus on the reliability before making these features.
Probably the scariest statement in this thread, given what we know about the reliability of software.
