A recent NRMA report has found that DRLs could prevent a quarter of all fatal daylight collisions and more than a quarter of fatal daytime pedestrian accidents.
As I've said before, you can be lit up like a council Christmas tree, even add fashing lights and sirens if you like, but if people dont actually LOOK then they will still crash into you.
As an example, as a postie I'm required to ride with my headlight on, I have a bright red bike with large fluro orange panniers on either side and I wear a high visibility green shirt and pants as well if it's raining. Basically you can see me from space. Yet people still pull out in front of me willy nilly all the time. People are just stupid and wrapped up in their own self importance.
So after my study I recommend banning stupid, self indulgent people from the road and thereby achieve a far greater drop in the road toll. But unfortunately that wont happen because most people would loose their licence.
