[Quietcars] Passenger defeatable systems.

[Michael Hingson]

Bob,

Correction accepted, but it is still the same thing.  It isn't nearly enough
just to know that a car is in motion.  My point is that the sounds we hear
today give more data than a car is moving.

Different cars make different sounds even if they come from the same
manufacturer.  Cars move at different speeds or they are of different ages
or they have other characteristics which have changed them over time so they
do not sound like others even made at the same time.

Your transmitter cannot give us the kind of information we receive today.
Again, it is important to approach the problem as if you want to insure that
any pedestrian should receive the same information whether they can see or
not.  In the case of persons who might not see a vehicle, (blind, cyclists,
etc.) simply knowing a moving vehicle is moving won't cut it.  Each vehicle
must emit acceptable sounds or we miss knowing all we need to know about our
environment.

Hi Mike,

I think there is a misunderstanding:

It isn't a receiver but a transmitter that works similar to the "panic
button" on the key rings of the vast majority of cars. In your travels, you
may have heard a regular, machine like "beep beep beep" that quickly ends,
somewhat randomly in or around parking lots. Often this is the owner who has
forgotten where they parked their car. So they push the "panic" button on
their keyfob and the receiver in the car "beeps" the horn and flashes the
lights. But "panic" beeps the horn at full volume.

The alert transmitter has no need for a button, it can send a signal just by
being carried. There is no need for a full-throated horn beep from the
receiving cars but something like the Volt, a modulated horn. Parked cars
would not need to respond, just those that are turned on and in gear. The
goal is every car is the receiver and any at risk pedestrian, blind, wheel
chair bound, elderly, and very young, pre-school, would or could by their
presence let the nearly universal vehicle receivers alert that there is an
at-risk pedestrian in the area. It is noise on demand by those who need it
when they need it. It amplifies what the white-cane means to sighted
drivers, something society already acknowledges as a valuable identifier.
