I know there have been suggests like this, with them linking up to all sorts of accounting software. I feel a much simpler system should be added.

After inputting a route, Waze asks you if this journey is for business or personal. If you select person, it adds the mileage to a business mileage log. That log simply adds up the mileage until it’s reset. I believe this will make it more useful for more people, a carer who has to submit their mileage weekly can use it, then reset it every Monday, where as someone like me who submits mileage once a year, just leaves it topping up all year, then resets every April.
