Every once in a while I get the urge to do this and have pursued making one with Grand Prix Legends track builder. Never got past elevation changes, sadly.
One right in my neighborhood

One using our downtown area. I managed to get it to go by most of the major downtown monuments, buildings, etc. The northern section looks a little boring, I know, but there’s a good deal of elevation change at the start and end of that portion.

And finally the one I made for Keith’s “propose your own US GP” when Austin was announced. This one isn’t streets so much as back-country roads.
