The number of traffic-related accidents suffered by MRR riders is interesting (and concerning), but I don't have enough data to get a handle on what it means.
But maybe not so relevant because most of the accidents happened nowhere near the MRR route
(Bayswater, Caulfield, Beach Road etc.)
We're in Blackburn South, and to be honest around here there are masses of bike-friendly roads, or big bike lanes. Most of the big roads running East West aren't great though and having a dedicated (i.e. no parking) bike lane on one of them would make a difference.
I've found that riding around Northcote and Clifton hill is very nice, and definitely in bits of the bayside suburbs, but there the bike-lanes/big wide streets are supplemented by the Ladies-who-lunch in their biggggggg 4WDs, so it's a bit of a gamble.
Obviously the inner-city suburbs are more conducive to cycling because of proximity, but if we all keep on cycling in our chosen suburbs, maybe we'll make other people think of doing it too.
When I travel along Highbury Road near us in the morning, I'm seeing an increased number of families cycling their kids to school - each time I pass them I think that maybe they'll grow up to be cycling to work.
