Again, not at all charitable. Your assumptions are baseless, seemingly motivated by little more than your mistrust that in the competence of people that have been actively working on this problem, many for years.
He said that he can "guarantee" Uber engineers gave it careful consideration (or at least more than people in this thread), but in truth he can do nothing of the sort. There are a plethora of examples where engineers and "engineers" didn't give a problem careful consideration and it got people killed. There is no rational basis for guaranteeing this is not one of them.
There is no "guarantee" that uber "engineers"/engineers put more thought into this than "their system is inconvienent, tear it out" or "we don't need their system because ours will be better, tear it out." Nobody can guarantee Uber engineers were not stupendously negligent until the investigation is complete. Anybody who thinks they can guarantee that has an irrational basis for thinking they can provide such a guarantee.
