Like in the Netherlands, a lot of people are able to speak English here in Germany too. Unlike France, they don't seem to be that uncomfortable with it.
While that may not be true for small rural areas, in most smaller cities you should be able to get around with English reasonably enough.
However, I don't think another country would benefit you much. In fact, I think people with Autism actually don't like and can't deal well with change, so you may be better off staying in the same continent.
