To be clear: I, personally, am really happy there are strong challengers in the car market. Also, I am speaking solely for myself.<p>The quote: &quot;Model S is designed to keep getting better over time&quot; reminds me of kaizen (1). It is a really awesome concept that not only can the car manufacturing process and technology keep getting better, but the cars can improve as well.<p>That being said: OTA update is REALLY FUCKING SCARY for cars. What if someone puts the wrong update in the queue accidentally? (2)<p>The historic attitude to modules in cars is also important. Modules run &quot;code&quot;, but it is treated as mechanically as possible. Could you imagine changing out a few pistons while driving? Probably not. This is a failure of imagination that is being addressed now!<p>It is a truism that Big, Old, Large companies are risk-averse. The downside to doing a bad OTA to a car is unlimited!<p>WRT to Tesla&#x27;s QA - I don&#x27;t know of anything that has been published in this regard. I would hope they are &quot;doing it right&quot;. I hope they are successful, and I hope everyone is inspired by their leadership and learns from them.<p>1: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kaizen" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kaizen</a> - Article claims it was introduced by American business people, but Japanese companies continuously improved it =D<p>2. <a href="http:&#x2F;&#x2F;www.techtimes.com&#x2F;articles&#x2F;90219&#x2F;20151001&#x2F;oops-sorry-microsoft-pushes-out-windows-7-test-patch-by-accident.htm" rel="nofollow">http:&#x2F;&#x2F;www.techtimes.com&#x2F;articles&#x2F;90219&#x2F;20151001&#x2F;oops-sorry-...</a>
