It will be better if routing can include erp/toll timing automatically. if user set to avoid erp/toll, but the timing of specific erp/toll is already over, then there is no need to avoid that route! So in this sense, route calculated from point A to point B will include erp/toll if the erp/toll on that route is already off, and it's calculated based on shortest road. If it's not, then will continue to navigate from A to B using the avoid erp/toll options automatically.
