So I downloaded the extension, just to see what it was about. It's a pain in the a**. I deleted it shortly thereafter. It kept telling me there were incidents when there were none. Single lane road incidents, mostly. And I checked in every way possible, even reloading the pages multiple times. Nothing. This happened on several worlds. Not to mention how intrusive the "helper" windows are. And you have to disable the ones you don't want on every world. More trouble than it's worth, in my opinion. Most of it is worthless to an experienced player. All of it was worthless to me. Gone, never to return. At least I finally fulfilled my curiosity about it.
