That still doesn't explain why they honk at red lights when no overtaking is going on.
It was a complete free-wheeling anarchy. It somehow worked quite well, though I understood why I was given a 24/7 driver. I could maybe have survived driving, but I would probably have killed someone else, by not following the unwritten rules.
It remains one of the most astonishing things I have ever seen!
Using group punishment to curb individual behaviour is always at risk of undermining group obedience.
I wonder what variables affect most whether the policy will be successful or detrimental.
