Dear DM43!
You're right. Many of us copy the pros, but we also add a few new ones. This is how I try. But I just want to add fresh data. The "TRAFFIBOX" craze makes me curious too. I'm not a fan of the speedcam extension anyway. I don't know how many speed cameras there are in your country ("Europe" - big "country")? What I think is unnecessary: Mobile speedometer, etc.
Finally: As an amateur, I often double the data. I don't have a fixed helper (policeman, etc.) Some professionals are helpful. Thanks to them!
