"Thank you for this post. I remember living in Austria and being fascisnated by the mechanism as a kid, this almost 40 years ago. Additionally, in most cases these windows have double glass for insulation."

"Mr. Noe. You seem offended or at least questioned by my comment and I want to emphasise that that is not my intention. The introduction of your text contains truthful information that puts the reader in the correct context but is not contained in the video. That is additional research that I'm not questioning more criticising. "

"The audio says that these lights are being used at only two train crossings in the city of Augsburg and are additional to the traditional lights. It is an initiative of a single city at tramway crossings and not considered for cars. Mr. Noe seems to have made additional research on the topic that is not part of this video. IMPO the context is very important in this video, specially considering Germany's street culture that is VERY different to USA's and although the majority of the interviewed people approve it, a few also comment that they hadn't even seen them or understood their purpose. One person even states that it is frightening to think that such an addiction to the smartphone exists that it is necessary to warn them before crossing the rails. Quoting Stuart Constantine: "(Additional) Warning lights at street level (for tramway crossings)" sounds a lot more acceptable than "traffic lights for smartphone users"."
