Now Waze always propose an option of routes without toll which is good, but not enough for me
Indeed, very often there is a compromise between full toll and no toll being relevant and worthy (cheaper than full toll, faster than no toll)

To improce the relevency of the routes proposal an adjustable ratio price/time should be considered

For exemple, for a ratio 1€/min, a toll road at 16€ for 20 min gain will be proposed but not another at 12€ for 10min gain compared to no toll option
