It's going to depend a lot on local pedestrian habits and on the available infrastructures: as a thought experiment say in State A people are never walking in the street, while in State B they are walking a lot, then the national increase in SUV will have no impact on pedestrian death in State A but will have on State B.
- robertlagrant 3y agoOnly if this is true. If the increase at night then it's unlikely to be because of SUVs, unless there's correlating evidence that shows it's states where SUVs are driven at night more. If there were evidence found that is linked to nighttime, e.g. because more people are crossing roads at night than before, or wearing less night-visible clothing than before, then that would be the place to start.
- bombcar 3y agoI wonder how much is actually attributable to people moving from one state to another, where the second state doesn't "drive the same" as where they're used to.
- Moldoteck 3y agothere may be different correlations, for example maybe suv's limit too much the visibility at night, but yes, we need more data

Or if you replace “people walk” by “people walk at night” in my example above… That is to say, there are many parameters at stake here, and you cannot infer or refute anything from the aggregated data.
