...it strikes me as almost surreal that they are floating the idea that consumers should 'trust them' in their ability to produce this technology safely and bug-free.
Please feel free to name any tech company that can produce bug-free systems. I'll wait.
I would be more worried about getting into a car made by a tech company that is used to a constant cycle of development and patching. A car running software by Adobe or Oracle? You couldn't pay me to drive in that. Even the majority of complaints against recent Ford cars is due to bad software for their Sync system... written by Microsoft. What if every bug in software written by Google, Apple, Microsoft, etc. got the media attention of an auto industry recall? We'd be inundated...
You have to remember that 1 recall = 1 bug in the auto industry. What other major industry (besides aerospace) has such a low instance of issues in their products that operate in horrendously harsh environments and temperature ranges are designed to last 10+ years?
