While I cannot answer that question I can tell you what our society and its governments have decided cyclists lives are not worth.
Cyclists lives are not worth the cost of installing truck side guards on all large trucks.
Cyclists lives are not worth the cost of developing and installing better mirror or camera monitoring systems for large trucks and all motor vehicles.
Cyclists lives are not worth the cost of designing and building roads that do not place cyclists in the path of other vehicles such as big trucks and then directs those vehicles into the cyclists.
Cyclists lives are not worth the cost of infrastructure that separates cyclists from motor vehicle traffic where appropriate such as on the most dangerous routes.
Cyclists lives are not worth the political will to require drivers, especially truck drivers, to have a legal responsibility to be able to see where their vehicle is going (and who they may be driving into and running over) before they go there.
And most importantly cyclists lives are not worth the elimination of the get out of jail free card that drivers that kill cyclists get for simply saying they didn't see the cyclist.
So what are are cyclists lives worth.
