As I've used slack over the last 5 years I've come to the conclusion that they have a quality problem of some sort. The software just behaves weird, especially in the voice and screen sharing areas.
It seems like their management runs the "quality via escalation" anti-pattern.
I've been alive long enough to see a considerable sample set of human drivers and I've got to say the bar Autopilot needs to exceed in order to save limb and life is incredibly low. Couple that with the fact that just here in SoCal Tesla has become a common sight, 273 crashes sounds like a hell of a lot of human suffering was avoided.
