I wonder what data, if any, this decision is based on. The only reference is to the organization Guide Dogs, which makes me think, maybe it's sufficient for them to emit noise that dogs (and children) can hear? On a semi-unrelated note, the other day I was thinking that difficult road sections should be fitted with beacons that cars can talk to in order to get a more accurate understanding of the roads during difficult weather situations, such as snow. Maybe such beacons could emit light/sound as well, when they're actively talking to a car, rather than the car itself having to emit noise. Though I understand that this puts the responsibility back in the hands of politicians/road authorities, which of course they don't want. Though to be fair, I get the reason for this decision. I was just looking forward to quieter cities.
