Thanks the detailed feedback, very helpful indeed.
Based on your suggestions, I’m now adding bus waypoints into the game. These act like stops to shape the route (except the bus doesn’t stop). I’m just testing this at the moment, but I think it does what you suggest.
I’ve been playing with the map size to make sure it also works on mobile. This has meant I’ve lost the top row where buildings didn’t spawn. I will see if I can add this back.
The current 2x speed is the same as the old 4x. I agreed the game was too slow at the start so made the default speed the old 2x (so the current 1/2x is the old 1x). It should be possible to add a further speed setting, but just need to make sure performance holds up.
