The folks at IAmsterdam have released a map that measures distances not in miles / kms but in time. Select a spot + a means of transportation + a desired travel time and it’ll show you how far away (in time) you can get.
From what I can tell European countries such as Belgium, France, Germany, etc. are also supported but New York (USA) and London (UK) for example aren’t.
💡 Back in 2017 MapBox created a likewise experiment named TimeMap
