You can write a web site about Coca Cola if you want. If it's just factual information that's all within fair use.
As long as we don't use the trademarked name 'Nürburgring' or their logo or an outline of the track in branding, it's all fair game. If we were to start selling t-shirts it would be a bit more tricky and we'd have to be pretty careful.
Can you mention the word "Nürburgring" anywhere on yout site, but just not in the website name/url? Please dont be angry, I am honestly trying tonumderstand the limits of what I can do on my own field of interest.
You can probably get away with using it in the URL too, but that becomes a gray area and really will depend on context. As soon as you want to put anything on merchandise though, it becomes really tricky.
An example, if you're a massive fan of a specific brand and start a forum at [brand]-fanclub.com as a hobby, for other fans to share info, you'll probably be ok, since that would be fair use. If you use the same name to start a paid website where people can buy a membership to get the latest news and you start selling branded t-shirts, you might get sued at some point.
Absolutely real. I want to know because there are large privately owned infrastructures in every country. Can one set up a website discussing it, and can one show pictures, maps, venues, tickets, etc., without being sued? (Or is only text and numbers permitted).
Did you get an agreememt with them or is it not an issue in Germany?
