I had this though many years ago, but unlike distance, travel time isn't necessarily symmetric, and so it isn't possible to represent time just by warping a conventional map as A->B and B->A will get the same warp.

And if the map allows for different travel modes, like train vs driving, I think it breaks entirely.

But this isn't to poop on the website -- I'm glad someone has taken the time to build a demo, even it it can't handle some cases.

You can turn on arrows that update as you move your mouse around (assumedly, signifying an origin). Not sure exactly what they do, but they do hint at potentially taking asymmetric distance into account.
