I can't be the only one that notices that not every bus or trolley shows up on this thing. I'll look up my route, the real time map will show the closest bus a being 15 minutes away, I'll step into a deli for coffee, and a bus will pass by while i'm no longer at the stop. I can't tell if buses are appearing/disappearing for a certain refresh of data out if certain buses never show up.
I know I shouldn't complain too much because at least they're trying, but it seems like the schedules are still the way to go.
I've used SEPTA Droid weregettingthere.com and the link on SEPTA's site (which I no longer see).
