Buses are the biggest trolls of the PTV network. That includes the “smart” buses. I’ve had the exact same thing happen to me before too, in the cold dark rain. Don’t miss it at all.

Once a colleague was dropping me off at a bus stop early and we saw my ("smart ") bus just about to leave well ahead of what the app said, and when I explained how unreliable the things are my colleague just gunned it and beat the bus in heavy traffic to drop me off a few stops later so I would definitely get on that bus.
