Yeah, I would be happier to have autonomous cars on the freeway than on other roads. There are usually no pedestrians on freeways that can be overlooked.
But I'm even happier that there are no autonomous cars driving by itself where I live right now.
Yes, this is how it is in Germany too and in my experience travelling it is like that in a lot of Europe.
Unmanned stations are a relatively recent thing here, so the first time I wanted to fill up at one I thought the pump was broken before I realised I have to pay first lol.
