In most cases I’ve seen, everyone just cooperates and takes turns in a similar fashion to when the traffic lights are working. Everyone slows down because they have the same worry as you. Just go slow and make eye contact with the people who also look like they’re in a position to go. It’s incredible how much your body language gives away just from eye contact.
You may even be lucky enough to see someone pull over and volunteer to control traffic.
Check out Sapiens by Yuval Noah Harrari. It’s my pick for the best non-fiction book and after reading it I found A Short History of Nearly Everything suggested as a similar read.
It’s a bit more dry than Bill Bryson’s work but a lot more informative. I listened to the audio book which was brilliant but would probably find it a lot harder to read.
It goes over the history of humans from around 70,000 years ago until current day. I would recommend everyone read this book to give them perspective on the things we find important and the rules we collectively chose to follow.
