-&gt; Billboards are pretty helpful. They often tell me I can get food by taking the next exit.<p>Usually I find the state-made info signs on the sides of freeways more informative than the advertisement billboards because it displays everything I need in one quick glance. The tiles of each &quot;food&quot; or gas or whatever option partitioned left or right, denoting which way I need to turn after the exit. That&#x27;s just me, though. And I&#x27;m a weirdo who sometimes drives with his phone in airplane mode and chases NPR on the dial.<p>-&gt; If there weren&#x27;t so much bullshit, you&#x27;d be less immune to it when it matters.<p>I don&#x27;t think this is necessarily true. It&#x27;s not like it&#x27;s 2 alternatives of content we&#x27;re talking about, one legitimate and one not. I think it&#x27;s more that there&#x27;s legitimate content that&#x27;s constantly getting interference from this extraneous and meaningless noise.
