Perhaps it's not a good time to discuss coroner's reports but:
When I sat on the City of Toronto Cyling Committee, we accepted a report frpm the coroner about bicycle/auto fatalities. It was long and detailed as such things are but one of the things that came out is that trucks and buses are more likely to be involved in fatal collisions and the other contributing factor was the difference in speed of the bicycle in relation to the motor vehicle.
With that in mind I try to ride on quiet, slow paths and roads far from large, speeding motor vehicles.
That of course does not take drunks into account, so I just assume that every driver is either drunk or so inattentive, that I am totally invisible.
It's worked so far.
