2．We humans are imperfect beings tending to make mistakes and basic errors of judgment．So we create technologies to help ourselves out．
Take the self-driving cars for example．The belief here is that the technology will improve safety．But this is a very bold assumption to make at this stage in its development，as the evidence to support the view simply is not there yet．The best data we have comes from tests conc1ucted over the course of 2016in California，a state which，it must be remembered，has a mild climate hardly representing global driving conditions．
Google's Waymo scored best，with one human intervention（介入）every 5，127 miles driven．This was an improvement on the year before，but nowhere near perfect．In all，Waymo's 60 testing vehicles drove about 10，597 miles in 2016-3，000 miles less than the annual US average per vehicle．Tesla performed much worse．The electric vehicle maker's four cars were tested on average 137 miles each that year，meeting with 45 human interventions per vehicle-or one roughly every three miles．Each Intervention represents an accident which was potentially avoided．
Given that most industry watchers believe the public will not tolerate any faults at all，none of this is encouraging．It is certainly true that the technology is improving．But it is also the case that self-driving cars have been around since the mid-1990s，with one vehicle achieving a 98.2 percent"autonomous driving percentage"even back then．
Even if the technical challenges can be overcome，unexpected negative externalities（外在因素）probably cannot．And we surely would not want to risk that when driving．
