You don&#x27;t need &quot;selfishness&quot; to create traffic jams. You need only &quot;latency in response&quot;; if you response less than instantaneously to the car in front of you slowing down, and you response less than instantaneously to the car in front of you speeding up (especially if you accelerate even a bit conservatively, let alone late), you very quickly get amplifying waves.<p>Your post, if we&#x27;re going to trade snarky political barbs, is a great example of how some people think that some magical form of &quot;regulation&quot; can regulate basic control theory right out of existence. Thinking that any form of regulation could somehow fix this is exactly the same as thinking that they could &quot;fix&quot; gravity. The physics is actually pretty simple at the core, even if the details are complicated. Anywhere you get negative feedback of a certain very, very popular and easy-to-hit form, you get waves. Can&#x27;t be stopped.
