The Domino Effect will occur.. where when a country innovates and then succeeds, other countries will follow in the footsteps of that country. IMO.. China, Japan, South Korea, Singapore, and Russia will most likely follow Germany in the future before other countries in the world
Everything is possible, and like what you have said domino effects once success being reached a lots of countries will follow and begin to embrace
this new innovated system. There's no doubt that some countries are also looking forward and only waiting for some big news about the success
of others that already adopting the system.
