EU is a densely populated place where having multiple charging networks of incomparable plugs will be horrible. When you are not happy with decisions the governments make, it usually means that you should be involved in the process of making the decisions. Europeans don't trust that the industry will always come up with the best solutions for the user, Americans usually don't trust the government doing something well…

In that case, having a random hodge-podge of competing connectors could have actual consequences. In practice though, there is not much…
