> Btw. do you really have traffic light buttons that don't do anything? Here in Berlin many automatic traffic lights have something that looks like a button but actually isn't one. Underneath is vibrating button that will show blind people that it's green without a sound. Many many people don't see that this is not a button, and don't think a moment about the blind sign (yellow ground, three black dots) on top of it and press it anyway, hoping it has an effect. Yes, the old ones really did nothing. I just can't understand why they were put there. I tried pressing (and holding) them a few times, they had no vibration or anything like that. They've started removing them as the new, functional ones are installed, but it's hard to change people's habits. The new ones both affect the traffic light timing and emit an audible signal for the blind.
