Well blind people are disabled aren't they? AND YOU HAVE TO BE LOUD WITH DISABLED PEOPLE IN CASE THEY DON'T UNDERSTAND, DON'T YOU?! :roll:
VTEC's Mark 4's are ridiculous in this respect too, with excessive volume and duration of door opening sound. Blind people aren't silly, they recognise the click of a door release, but their world is being overrun with stupid electronic sounds to 'denote' something happening.
Well they already know, because the something happening has a sound it makes already which 'denotes' it happening!
Not all blind people have perfect hearing, nor are all trains continuously silent at the point of a single 'click of a door release' occuring for it to be unmistakably heard. I presume that you have normal vision and hearing given your disregard of the sensory shortcomings of others.
