I don't like how the girl's death became a focus point for a crusade against cars in general (even though I'm a fan on public transport myself). By most measures, London's air is great as it is on average. However, some sources of pollution are local, like a big busy road, and the girl, unfortunately, lived near one (the article mentions she lived near South Circular Road). Trying to make the air clean on average is really counterproductive compared to, say, making buffer zones around roads with more greenery, tackling local pollution instead of averages.
