Fuel / Trip Tracker
Waze already does an excellent job with navigation and fuel price awareness, but adding a built-in Fuel and Trip Tracker would make it even more powerful for everyday drivers. Being able to log fuel-ups directly in the app, including litres, cost, and odometer readings, would allow Waze to automatically calculate fuel consumption, cost per kilometre, and running averages over time.
A simple trip tracking feature would also be hugely valuable. Drivers could start and end trips with a single tap, tag them as work, personal, or road trips, and receive an automatic summary showing distance, duration, and estimated fuel usage. This would be especially useful for people who need to keep logbooks or track travel for budgeting and reimbursement purposes.
