Whilst I do use Waze. I find it annoying sometimes. It doesn’t give me an option of “fuel saving route” just the fastest. For example; been doing a regular journey to a destination for 2 years and only just found out (more fool me 🤣) that if I use the alternate non motorway route it would save me around 40% mileage. Albeit a rather short route overall. 40miles vs 28. Still a massive difference. Especially when I barely get 40 miles for a tenner petrol.
