This is a great technology and has clearly made great strides, but at this time it is hard to trust. These vehicles have had many problems that human drivers do not. Problems with maps can cause dozens of them to collect in dead end alleys. They may stop on busy one lane roads. They consistently fail to react appropriately to responders and emergency situations. And even if the supposedly reliable recording and reporting work out it is not always clear who is responsible when things go wrong. Simply not killing as often as humans is not good enough for mass deployment of this technology.
