Good public transport systems provide even better benefits for points 1 (accidents involving subways are probably still going to be rarer than for self-driving cars), 2 (you don't even need fossil fuels for subways / trams), and 5. Arguably you don't lose much on point 3 either, except that you may have to walk a few minutes to/from the nearest stop (which is probably good from a public health standpoint anyway). I agree that this only applies in cities though, and public transport may not help much in rural areas.
