I can see why you think I was making that implicit claim, though that wasn't quite the point I was trying to make.

I don't know to what extent the regulation mentioned in the Wikipedia article I linked to was influenced by industry lobbying versus concern about other sorts of risks to infrastructure or public safety. I'm not sure whether the precise cause of the passage of such regulation is that relevant to the regulation's durability in the face of potential benefits from adoption of new technology. Maybe it is, but the precise example of "limit[ing cars] to the same speed as horses" in the original post seems to imply that was something that didn't happen, not just something that did happen for different reasons.
