Most of the time I end up deciding how I'm going to get to my destination by considering the time and monetary cost of the transportation options.
The saying goes "Time is Money".
For example: if you valued your time at $50/hour. Despite a Taxi/Uber/magic carpet costing you $25, it might save you 40 minutes in comparison to walking. Or it might even be more cost/time effective to just walk.
GPS navigators only give options based on time without considering the monetary costs of the options available. (eg. Google Maps, Apple Maps).
My idea is to utilize existing navigation services but instead tailor the total "cost" based on the user's self valuation of time.
When selecting your desired destination. A monetary cost will be applied to all options.
Example:
From A to B
Bus: $3.50 ticket + $50/hr * 10 minutes = $11.85
Walk: $50/hr * 20 minutes = $16.70

You need to put a dollar value on exercise.
