When riding a motorcycle on very twisty/technical roads, audio is all any rider could possibly use. It is too dangerous and not practical to be looking down at WAZE screen or operating WAZE screen (with gloves on). Therefore having screen on in this context is useless and drains phone battery unnecessarily. Regarding reporting of road hazards and speed traps, the most preferred/safest/practical thing to do is pull over, remove gloves and then operate phone.
