Can you somehow add content to these lists? I think I didn’t see Galaxus (european Amazon alternative) on there anywhere :)

I’ve driven the same general route a few times and even then, it has been quite reliable. As mentioned, it can depend on the cities and stuff, so you’re best trying it out for yourself :)

I’d like to recommend ‘Magic Earth’ to everyone, who wants a privacy respecting Maps alternative with trafic data. I used it on several >500km trips and it only misguided me once. It uses OSM maps and can navigate offline.
