It's quite decent in the UK. But I wish it had more customisability. Sometimes it cannot understand that I'd rather walk 15 minutes than buy a bus ticket for a 3 minute bus ride. But if someone was disabled and got free bus rides because of that, then of course it would make sense for them.

It can tap into bus data to see when it's late and stuff. But sometimes the bus company messes up the data. Oops.
