If you are parked fouling a trolley line that should be your problem. Philadelphia has six street trolley routes left over from the days when trolleys ruled the city. The Route 15, which passes a block my current house, was originally a trolley but was converted to a bus route at some point. Maybe a decade ago it was converted back to a trolley route using, in part, restored vintage cars. I used to ride those things back in the day, until they were replaced in the early 80s by modern cars made by Kawasaki.
We also have "trackless trolleys" (a/k/a "trolley busses"). They are electric busses that draw power from tandem overheard wires. Three routes remain.
