Hi again, Bob -- a few questions. I will preface by saying that I hope
you don't read any animosity into my words. Like you, I am interested
in solving this issue of quiet cars. I respect that you have a
different mindset from many on this list, one as a hybrid car owner,
two as a sighted driver, and three as an engineer who has been working
on an idea to solving this dilemma. I thank you for providing those
three viewpoints.

You note in the first set of effects that the noise generator gives
the driver a rating of zero, i.e. no change, because the constant
noise from a vehicle would block other sounds. This is the same as
today, correct? What sounds are you hoping to hear in a quiet car that
would be useful to you to know to hit the brakes? It seems that
installing a constant noise in a hybrid is no different from constant
noise emitted by yesterday's gas-powered, combustion engines.
You then talk about how including hybrid owners in discussion leads to
inaccurate data, but then suggest we involve them. I may be mis-
reading here, but I'm confused. I would agree that drivers are a key
player in these situations and that their views need to be taken into
account, but you're saying that when that was done in the past, the
views represented didn't reflect yours as a hybrid driver?
Further, in response to knowing when the system fails...
> You might notice that vehicles are no longer 'bleeping' their horn.
I as a blind person would know that my device has failed when horns
aren't beeping. But what if the system fails in an individual car?
One, how is the driver to know that his system isn't alerting blind
pedestrians, when he may not take time to notice there are blind folks
around him who may have the receiver? Two, what will encourage him to
get this fixed? Here's an example. I am crossing the street; a hybrid
approaches, and my device is working but his is not. The horn doesn't
beep, and--let's be optimistic--I narrowly miss being hit. How am I,
as a blind person, to report that incident and link it to a specific
driver? I can't see his plate, I can't see what kind of car he has, etc.
We can't throw out an idea on the basis of device failure -- after
all, it's inherent in any technology. But these are some questions to
which I hope you or others on this list may have some ideas about
solving.
One more thing...

Are you suggesting that as a biker and pedestrian that you don't use
sound emitted by vehicles when on the street? If you're biking, don't
you hear that car coming from behind you so you know to move right,
out of his way, or look to see if that car is trying to pass? I cycle
too, and find that I use sound just as much as my sighted counterparts
when vehicles approach from behind.
Thanks, Bob, for always responding to our questions.
