&gt; <i>driver aids have been implicated in causing more severe winter accidents, eg. this [1] 100-car pile-up in Sweden a few years back.</i><p>The linked article, AFAICT, doesn&#x27;t implicate driver aids in the accident, at all. (It&#x27;s a rather short article, and the video doesn&#x27;t mention anything about driver aids either.) Am I missing something?
