Unfortunately this seem to have become par for the course on HN. Disagree, but don&#x27;t say why so no one can counteract your arguments. Anyone who looks at self-driving cars from an engineering perspective know that there are still many challenges.<p>Congestion is more a factor of tolerance than technology.  As demand and tolerance for long commutes go up we might actually see less efficiency. [0]<p>It&#x27;s still hard to match the human mind, especially without significant overhead. [1]<p>Cars are a compromise and aren&#x27;t as efficient as pods or as fast as trains. [2]<p>Current electric vehicle technology can only drive you for about an hour at relativly slow train speed, at which point you&#x27;ll have to charge for about as long. [3]<p>etc.<p>The car really is the weakest link in the &quot;self-driving car&quot;. Which isn&#x27;t unexpected because it&#x27;s engineered around the driver.<p>[0] <a href="http:&#x2F;&#x2F;journalistsresource.org&#x2F;studies&#x2F;environment&#x2F;transportation&#x2F;fundamental-law-road-congestion-evidence-u-s-cities" rel="nofollow">http:&#x2F;&#x2F;journalistsresource.org&#x2F;studies&#x2F;environment&#x2F;transport...</a><p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=kp3ik5f3-2c" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=kp3ik5f3-2c</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ULTra_(rapid_transit)" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ULTra_(rapid_transit)</a><p>[3] <a href="http:&#x2F;&#x2F;imagizer.imageshack.us&#x2F;v2&#x2F;1024x768q90&#x2F;203&#x2F;modelsrange.png" rel="nofollow">http:&#x2F;&#x2F;imagizer.imageshack.us&#x2F;v2&#x2F;1024x768q90&#x2F;203&#x2F;modelsrange...</a>
