Its impossible to covered every road in lights and it can get very dark when you are far away from a city. Same with public transit. I am all for it, but it’s only reasonable in more densely populated areas. There just won’t be enough people using it in th middle of nowhere to just something like that much less staff it.
Meanwhile helping cars see people even in those less common and more difficult situations is a good thing. Why would you NOT want your car to be safer for others around you?
