I'll add Nürburgring to the list, and that'll be the 6th time the N is used. The person following me with something starting with a G, will be only the 3rd person to do so.
Other letters that have been used extensively, and that we might be wise to avoid if we want to keep the game alive, are I (9 times - there are a lot of Italian drivers whose names end with an I, but not so many drivers whose names start with one), S (9 times - but there are more options here), E (8 times), A (7 times), R and N (6 times) and Y (5 times).
That's all from the Statistics Department for now.
