If we're talking about safety, then the injury risk is kind of important.

The paper did not do any research on traction or driver overconfidence so remarks about these are just casual commentary, but for the record, the mention of AWD traction is not particularly relevant to avoiding traffic accidents:

"While these important results imply that AWD shall not be considered as a safety feature, it should be kept in mind that AWD does have benefits in terms of improved traction compared to 2WD cars, for instance on icy uphills, snowdrifts and, depending on the vehicle, in off-road driving"

"AWD technologies should be further developed so that slippery road conditions are not disguised by the improved traction provided by AWD."

AWD provides more traction, and thus more control than 2WD. I have no desire to give that up because some people take more control to mean "I can go faster." You're welcome to come to a different conclusion.
