Laws and regulations to force hybrid and pure electric car makers develops vehicles that emit a noise to alert blind people to their presence are under consideration.

You're probably familiar with the recent problems with quiet and silent vehicles and people with less-than-perfect sight. The National Federation of the Blind (NFB) has been on the case for a while, but there is one angle of their advocacy I didn't know about until Harper's printed the lyrics. The lyrics to what, you might ask? Well, the lyrics to a reworked version of the 1943 song Surry With the Fringe on Top (from Oklahoma!) and used by the NFB's Committee on Automobile and Pedestrian Safety.
