Why Tesla removed radar and ultrasonic sensors [video]
I thought it was telling that Andrej immediately "reframed" the question because Lex asked the "wrong question". This is a classic evasion technique one learns from experience and/or media training. Lex's comment immediately after was a clever and gentle dig at Andrej's response.It seemed like all the "full cost" negatives Andrej mentioned were related to Tesla's ability to execute, and not what would actually produce better results. Tesla would have to be able to reliably procure parts, write reliable firmware, create designs and processes that won't increase unexpected assembly line stops, etc.Regarding results, the best Andrej can do is, "In this case, we looked at using it and not using it, and the delta was not massive." In other words, the results are better, but not enough to make up for the fact that Telsa can't support additional sensors without incurring a prohibitive amount of additional risk to Tesla. Risk to passengers doesn't appear to be a consideration.
