Quite a few navigation systems (standalone and apps) offer a function to simulate travelling on a selected route. Which means that the system doesn’t use the real GPS position but simulates moving along the current route.
With all the views, instructions and functions availabe just as you really would drive along that route. Usually with a “time zoom”-option the be able to play the simulation faster than you would in real life (with simulated speeds from 50 up to more than 300 km/h, sometimes quickly changeable directly in the navigation view during simulation) without being forced for “test rides” to identify your most preferred configuration settings.
I would be great to have such a function in the Kurviger app because this is a good way to try different things and to get used to the views and behaviours (like displayed or spoken instructions) of the apps. Especially but not only for beginners. More experienced users could use this function for getting deeper in the results of the different settings for the app (like zoom factors, layers, map appearances or colours).
