this is widely accpeted in the transportation engineering community.
Sharrows in the USA need to morph into unmistakeable signs to both drivers and bicyclists that bicyclists have FULL use of the lane.
I still don't think they should only be used on low speed roads. There are many roads over 30mph that would benefit with easily implemented sharrows - roads that would unlikely be widened anytime soon. There are also roads that are over 30mph that would not benefit with traffic separation - for example roads with frequent intersections.
