Roman example was to show the silliness of your argument, that the only way to get around or move things is by car or truck, when for millennia humans have used other forms of transport for the exact same purpose and effect.

Milk used to be delivered by horse and cart. Auspost now uses small epowered buggies for deliveries. Many countries use canal boats for deliveries. Humans adapt and always find solutions is the point, so no, things wouldn't just stop.

Our society is built in recent times to prioritise motor vehicles, so that is what is currently in use, but it is unsustainable in the long run both socially and environmentally. There are better ways and other methods of transport that would be cheaper, greener and more efficient if we build infrastructure to support them. That's what this thread is about, if you remember.

You also keep thinking we are advocating to get rid of cars and trucks, but nobody said that.

So you keep enjoying sitting in traffic congestion, thinking how wonderful it is to be in a car, and I will continue to ride in fresh air, sunshine with no traffic. I can see you aren't interested in having an open mind to your thoughts, so I think we can agree to disagree and move on. Good luck.
