Blind people must surely be more aware of taxis than the average Joe. We use them as a sort of everycar. You can learn a little about the internation taxi services of Londan.
Several cities--an e-friend in Milwaukee mentioned this to me--supply vouchers for blind and disabled people who cannot afford to use cabs regularly.
In Lafayette, Louisiana, each time I use the paratransit van is said to cost roughly $15. I wish I could have that $15 or even only $10 to spend as I wished.
Others might argue that where high quality mass-transit exists, we all should use it. Of course, the purveyors of the bus system in Lafayette would need to undergo some major sensitivity training--which wouldn't hurt the taxi drivers either. I am informed that in metropolitan areas using subways, conditions vary.
Washington, D.C. has an outstanding system with adequate tactile arnings for blind users approaching the edges of platforms. In New York City and Boston, some blind commuters become seriously injured or even die because of inadequate safety precautions.
This issue was debated, if memory serves, by several major consumer groups of and for the blind. The arguments were, on the one hand, that sighted people have environmental safeguards, colored lines, lighted markers, to assist them; and, on the other, proper cane technique or a properly trained service animal should be sufficient to insure a commuter's safety. This argument became rather heated in the mid 90s when Washington, D.C. was considering installing tactile markers for blind subway users at a rather significant cost.
In my opinion, anything I can have to make me feel safe, is fine with me. If sighted people think this means that I am "a helpless, dependent, complaining, hand-out-grabber"--well, tough titty!
