I'm a pretty big fan of Tesla in general but this aspect has always left me baffled. I am a software engineer and work on a system that is not 1/1000000th as critical as a self driving system. If my system crashes or has a bug no one is at risk of injury or death. Yet I would never dream of releasing an update or feature to our clients to test or QA. Our clients are paying us to give them a system that is tested and works. Its like Tesla has somehow convinced everyone that is no longer the norm and being tester/QA is part of the deal.
