I found this column about a dangerous stretch of road in Ohio, and the cyclists who ride there. Unfortunately the title of the column is " Bicyclists should do their part for safety ". I believe cyclists should do their part for safety, but the greatest threat many cyclists face is not under their control.
Late in the column one cyclist says a 3 foot law, (like we have in Wisconsin), would help make cyclists safer. He points out that the Ohio legislature was working on a bill that would require patrons at strip clubs to stay at least 6 feet from strippers. He believes cyclists should get at least some protection from the legislature, even if it is only half the protection strippers get from their customers. The columnist says " That would help, but only if the driver can see the bicyclist and has time to react."
I say it might help but only if you can convince the authorities to enforce the law once it takes effect.
