With this in mind I don't agree that we should stop autonomous driving because of these accidents. Who knows how many accidents have been avoided self-driving so far, cutting off the technology or saying that "it's not there yet" is not a good way forward in my opinion.
I agree with this conclusion. The advantages of computers driving instead of humans are numerous:
Computers can utilize sensory information not accessible to humans like radar.
Weather conditions affect computers less than humans because of point 1 and because they can be programmed to take them into account from which programming they will not deviate for human reasons.
Computers can efficiently share information about general road conditions with other vehicles and other online sources.
Computers can efficiently share information about road conditions specific to the present moment with other vehicles, online sources or the road itself including the precise position of other vehicles or obstacles on or defects in the road.
Data gathered by an AI driving a vehicle can be used by a cloud service doing deep learning making it possible for better versions of said AI to be installed on computers on every vehicle using the cloud service.
In my opinion, based on the stats you have referred to, it would make sense to continue and expand the use of self-driving vehicles in part to accelerate development in the field. Massive gains in traffic safety, road infrastructure costs and life and limb can be expected.
