Or by designing roads around encouraging bicycling and pedestrian safety:

- exclusive traffic phase for pedestrians and cyclists (all automobiles receive a red light) at intersections

- protected bicycle lanes

- no right turn on red

- allow the Idaho stop

Of course, all of this is predicated on having places where people actually want to walk/bicycle.

As opposed to the typical suburban wasteland of concrete, tarmac, strip malls and exhaust fumes.

Cars kill. Sometimes even directly.
