Good—could be great

Accurate-to-the-minute bus locations—but sometimes a minute is all it takes to miss the bus. In my dreams, there would be a setting for people like me that put the buses locations about a minute ahead of where they actually are.

More realistically, it would be great if it opened up to your location, instead of a zoomed-out view of the whole bus network.

Its great to turn bus routes on and off on the map (there are only a handful I use regularly), but I wish I could do the same at bus stops. (There are a dozen routes that use this stop, but I only care when two of them are going to be here.)

This is a good start, and with just the data it already has and a couple tweaks, it could be great.
