I've encountered many reports of issues with safety regarding autopilot or breakdown/less repairability of the vehicles due to lack of experience in design, but

  Just the choice of using NCA batteries over NCM could be viewed as a safety cost cutting measure. Here's a scientific paper about the safety of various battery chemistries (warning, PDF): https://res.mdpi.com/wevj/wevj-06-00572/article_deploy/wevj-06-00572.pdf https://res.mdpi.com/wevj/wevj-06-00572/article_deploy/wevj-... Summery is that, compared to NCM, NCA inhibits thermal runaway at much lower temperatures, offers significantly less short circuit resistance, slightly less overcharge buffer before thermal runaway, significantly faster thermal runaway after overcharge buffer is exhausted. The result of thermal runaway is fire or explosion.
