In a plane, which can move in 3 dimensions, horizontal separation is measured in &lt;i&gt;minutes&lt;/i&gt; and it&amp;#x27;s not that common to be following immediately behind another plane at the same speed: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Separation_(aeronautics)#Horizontal_separation&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Separation_(aeronautics)#Horiz...&lt;/a&gt;</text><parent_chain><item><author>chrisseaton</author><text>&amp;gt; There&amp;#x27;s virtually no way of being both attentive and passive for long periods of time.&lt;p&gt;How do aircraft pilots manage it?</text></item><item><author>c3534l</author><text>The best way to stay attentive behind the wheel is to actually be the one driving.

The recommended procedure for handling an emergency situation is to pull the checklist for that situation before starting to ensure you don&amp;#x27;t miss anything. Even urgent situations, like a TCAS alert, will often give 30 seconds warning. By contrast, this driver had roughly 2 seconds to notice that the autopilot was silently failing to handle the situation and to apply the brakes to prevent a collision.</text><parent_chain><item><author>chrisseaton</author><text>&amp;gt; There&amp;#x27;s virtually no way of being both attentive and passive for long periods of time.&lt;p&gt;How do aircraft pilots manage it?</text></item><item><author>c3534l</author><text>The best way to stay attentive behind the wheel is to actually be the one driving.
