There was an article yesterday also dubiously claiming "Cars are killing more people – and driverless cars won't solve the problem." It seems ironic that just as self driving tech is getting good enough to maybe make a difference you get all these articles asserting it'll never work.
Looking down the list of accidents in the article, basically all of them apart from maybe deliberate road rage could be prevented by self driving tech within a decade or two. Stopping them by taking most cars of the road in the same period on the other hand isn't going to happen.
