Not all in urban settings but these are public roads made into awsome race tracks.

Isle of Man TT, I don’t even like bikes that much but I love watching them zoom round here.
4
Le Mans, those dam chicanes spoilt it a bit but it’s still awesome
3
Targa Florio, not much chance of blue flags here. (to be honest I’m a bit surprised no one mentioned it yet)

Monaco, This track is so tight, I love the way they keep driving it when the cars have long since out grown it, and the prestige is unmatched

AVUS, home of the ultimate hairpin and “The wall of death” If Tilke had no safety rules to worry about, he’d probably come up with a new AVUS. And it’s kick ass in a game (find it for Rfactor). The ultimate engineer’s track
It seems I like them old, real old. sorry for any spelling errors.
