It is bad form to use a strawman argument (very few people criticizing Uber have argued that the victim was blameless, at least from what I've seen on HN), though perhaps some would take extra offense when the argument involves a dead person, who among other issues hasn't been able to speak in her defense.

I can't speak for Uber and its engineering team, but I doubt they find it flattering when people defend their AV performance by comparing it to 70-year old grandmas.
