If &quot;feels safe&quot; is our goal, we&#x27;re gonna be chasing those taillights forever. :&#x2F;<p>I live on an <i>incredibly</i> well lit block in a very well lit part of SF. [0] I&#x27;m a couple of blocks away from a substantially less well lit block. [1] It&#x27;s <i>much</i> more enjoyable to walk through the less well lit block than the more well lit ones. I expect that it&#x27;s <i>significantly</i> nicer for the folks living in the apartments on that block, too.<p>Light pollution <i>also</i> affects people who aren&#x27;t astronomers. :(<p>[0] Seriously, you can <i>easily</i> read a book on the street in just about any part of the TL. On my block, the fixtures are 50-&gt;75% as bright as daylight.<p>[1] That is to say, you&#x27;d have to strain your eyes to read a book on that section of the street.
