Sarah,
I am not surprised about people voting down the 2007 resolution to put
effort and funding behing a car the blind can drive. I would have voted
against it myself.
It is very good to stimulate and promote innovative research into this type
of thing, but there are more tangible things to be concerned with, so the
resolution didn't pass, if I remember correctly.
I can't emphasize enough that this kind of research and development is
exciting, and important.
Skepticism will always come up about these things though, because we don't
know what the future could hold for a car the blind can drive.
I don't understand how blind people expect to drive safely, sure we know we
are capable of deciding this and that, and of taking control and making
driving decisions. But aren't we now fighting to be able to cross streets
safely? Hybrid cars should be making noise so we know what to do as
pedestrians, but I wonder how much noise things will need to make for us to
drive safely.
If cars can have sensord to detect all things on the road for a blind
driver, why not work on a similar thing for blind pedestrians to cross
safely?
I don't expect an answer on that question, since I am being a bit of a
devil's advocate. Pedestrian safety should rest with car manufacturers, but
if we are fighting this battle with hybrids today, and keep on with a
mission for a blind driver car, we will be questioned, if not ridiculed.
