I remember that from when we discussed that here the first time around. That's the same video, so I wonder if it's still in prototype or if it's actually coming out?
In any case, what I really wonder is whether the distance is adjustable for the mounting height. It looks like it's maybe only about 18-20 inches from the wheel, when the law in many states and a safer distance everywhere is three feet from the rider. It seems to me that a car could easily observe the line and still buzz the cyclist, particularly if they have wider handlebars.
