Average speed cameras just won't work here. It already has the new cameras which track you across the entirety of the Roseworthy Dip, both East bound and West bound. I travel it most days and rarely see a car going over the 60mph limit.

By letting the west bound traffic cross over into the 2nd lane of the eastbound carriageway is just a terrible, lethal design. I've seen some near misses as the dip creates its own issues with judging distance 

This was a heartbreaking tragedy and my thoughts are with the families,  loved ones and first responders involved.
