While I appreciate how the article brings up the history of the use of roads, times do change. Despite their dire last sentence, humans have always altered their behavior for the sake of their created machines. This is a trade-off with progress. This is why we have rules to allow shared use of the road.
Automated cars are simply a new addition to this. Travel to countries where there are no enforced road rules and see how efficiently traffic flows. It's horrible. The idea that we don't want to change behaviors for new tools is silly. If that's really their assertion, they need to stop posting in the internet and only share their news in the public square, that they walked too.
