[SystemSafety] a public beta phase ???

Words are very important, calling something an 'autopilot', rather than 'driver assist' is probably a mistake. Using the term 'beta' to engender a degree of caution in the user base is, conversely, probably a good idea. Thinking about it in terms of risk homeostasis, Tesla appears to be trying to put a big virtual spike in the center of their steering wheel :)

In one camp, Tesla and many other carmakers believe the best route to a truly driverless car is a step-by-step approach where the vehicle gradually extends control over more functions and in more settings. Tesla’s limited Autopilot system is currently in what it calls “a public beta phase,” with new features arriving in over-the-air software updates."
> PUBLIC BETA PHASE!!! Jesus wept are these people serious! The subtext here is silicon Valley 20 something phone app developers programming life critical systems where a "blue screen of death" is no longer a giggle but means real death. Buy a Tesla and your life is in the hands of a BETA release? WHAT?

I sincerely hope that we don't have to watch any children die before US regulators force Musk to put some adults in his development shop.
