the death of a local (Miami) cyclist,

The recent death of 37 year old Andy Cohen, a recent example of an ongoing trend in Miami of terrible unfortunate hit and runs involving cyclists dying. Local bicycle blog Miami Bike Scene drummed interest in the death with an impressive moving memorial.
With a large focus after the unfortunate death of Christophe Le Canne, and the subsequent detention in punishment for it, demonstrate in the interim that retribution is not a sufficient method for deterring accidents involving vehicles hitting cyclists.
The rights of people to use roads at their pleasure have been protected--even if only superficially by laws and regulation. But these laws alone and without a concerted effort focused at deterring the circumstance, rather than condemning its occurrence, surely persist it.
Having personally witnessed promises made about the very road of this more recent bicycle death on the Rickenbacker Causeway, I recognize the frustration of those in the community who would publicly demand the living rights of all people. Bicyclists, though a perceived nuisance to drivers, represent a legitimate and growing demographic of transported people. Public transportation and a personal car are not always sufficient and necessary means of meeting our transportation needs.

If the community gathers to demand justice in response to this recent of various bicycle deaths, it would do best though to focus not on response, rather sharply at the inability of the ongoing approach to adequately or noticeable promote the safety of that community.
The answer is not simple, but do we even ask the right questions of those who act in our names? It is unreasonable for government to approach problem solving by the paradigm of costly studies and lofty schemes promoted by public funds seeking firms.
While drivers mostly advance the conventional wisdom that bicycles belong on the sidewalk, any bicyclist worth their damn uses the streets to get places otherwise far away.  They would tell you the impracticality of relying on the sidewalk.

There are probably many ways to get the idea in the minds of Miami drivers that bicyclists should be respect. (everyone should be respected) Some cheesy in part of me like sharrows; others like bike lanes. More ubiquitous exposure will certainly have its place and unfortunately so too will the accidents.
