These all seem like nitpicks. Maps transit is still the best way to figure out to go between points and it works in multiple countries with the same interface.
And to be fair, it'd be cool if these - comparatively small - changes happen. But using transit routing frequently here, I have no real complaints with it. It works fine.
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.
