It depends on how you want to measure your safety when driven in one of these?
Do you want them to beat a drunk driver, or an average, non-impaired human? If you got into a cab and cab driver was obviously drunk, would you ride along or get out asap?
By "letting" them compare to an "average" (skewed by impaired drivers' incidents), we are letting them appear much better than an average, non-impaired driver, whereas they might be, or might not be (numbers clearly suggest they'd still beat them, but not by this much).
