I don’t think anybody is arguing speed limits should be abolished. At least not in any general sense. But, it’s plain enough to see that speed limits on some roads are wrong.

I-495 in VA is a prime example. It’s posted at 55mph and traffic regularly flows faster (or slower, during rush hour). It really needs variable limits based on traffic volume instead of a dumb 55.

I'm not suggesting getting rid of speed limits.

I was objecting to the idea that there is no natural speed, and that the group will "just escalate". Nothing else.
