Generally cities are scaled 1:3 and roadways are scaled 1:20. They do have the trolleys in SF, but I don't think they spawn in the bit that you drove in.
Yup! I had some large brain farts on the area since it's been a couple of years since I've seen it. I meant to say it was a 1 to 3 scale time within cities since it took me almost an hour in game to leave Modesto city limits due to the number of lights and surprisingly decent road layout. Next time I will pull up a tab with Google Maps to correct some of my own errors about details with scaling. I do know these historic streetcars should be able to run through the Embarcadero on the same track as MUNI as they come from Market (or however they implemented market by the Highway 80 entrance) and loops back just before Fisherman's Wharf (100% missing in game sadly). The cable car trolleys are still in game off their representation of Hyde St which I didn't go to in this video. Thank you for watching though!
