It's usually a legal risk deferrer decision to buy the ATM casing with Braille. Someone pointed out that Drive-Ups and Walk-Ups are the same, which it true for the internals but not Drive-Ups casing and moldings, which are adjusted for the average eye level of a person in a car, plus recessed, tiled monitors, etc.
Basically, it costs x,xxx.xx to get the casing with Braille, and legal risk is valued at xx,xxx.xx (i.e. someone suing them because it doesn't have Braille).
Better safe then sorry in risk management. I wouldn't view this is a lapse in deign decision, more of an obscure design decision.
overdesigned rather than poorly designed. even if nobody can use it, it's just an extraneous feature. an atm built into the concrete that you'd have to stop short of and get out of your car to use. now that would be poorly designed. s.
