If you're interested in a simple Logo programming project for kids, it was a fun, visually pleasing project. If only the public transport companies realised the value in having time-proportional maps.
Would be kind of nice for when i click the point that all the points distort based on that point instead of globally trying to position each point relative to every other point.

(I ignore the idea of traveling by car in thickly populated areas of Manhattan and Brooklyn; it only makes sense if you value your personal space way more than you value both your money and time, and don't have to park.)
Whether it accurately does that, as in your Bushwick Flatbush example, I don't know.
The thing remains weird nevertheless. I'd assume that if you click a point at this mode, the point stays put, because the time from this point to this point remains zero and does not change. But the map twitches so that the point under cursor / tap moves away. I suspect that the map shows some other kind of approximation, not the time to the point clicked. Likely the grid that defines effective times is somehow sparse, and approximating the distortion well when a click hits rather away from a node is hard. But that would still be weird, because I suppose that points like airports and train terminals should definitely be major nodes of that grid.

However in the real city the transit speed at any point is not isotropic, the space is 3-D, and some paths are forbidden (getting on-off the train between stops).
