Indeed. Similarly, we may eventually need to contend with the fact that posted speed limits are, in most jurisdictions that I know, at least 5 to 10 MPH lower than the enforced limit. Virtually all human drivers drive some small amount over posted speed limits. If we were to force all autonomous drive systems to always perform full stops and always obey the speed limit, the human drivers mixed among them will lose their minds. At least so far, NHTSA has not said that Tesla and others need to ensure that in autonomous drive modes, the speed limit may not be exceeded.
