Currently, Waze Motorcycle Mode calculates ETA purely as continuous kinetic driving time (distance / traffic speed), assuming the rider never stops and experiences zero physical fatigue.

On medium and long-distance rides (e.g., 200–600+ km), real-world arrival times are consistently off by 20%–35% due to factors unique to two-wheelers:

1. Fixed Operational Overhead:
   Every motorcycle stop (fuel/hydration) requires 15–20 minutes due to mandatory gear handling (helmet, gloves, earplugs, rain gear) and stationary eating/drinking.

2. Non-Linear Fatigue & Pacing:
   Unlike car drivers, rider physical strain (wind resistance, balance, hyper-vigilance) compounds over time. Rest frequency naturally increases on long legs (e.g., from once every 200 km early on, to every 100–120 km after 4 hours of riding).

3. Fuel Tank & Consumption Profiling:
   Allow riders to input tank capacity (L) and average consumption to automatically suggest optimal fuel stops along the route and fold them into the total trip duration.

4. Weather & AI Adaptation:

5. Weather Multiplier: Automatically adjust speed projections and add rest buffers when routing through rain, fog, or extreme temperatures.

6. Adaptive Learning: Learn individual rider stopping habits and average break durations to calculate an accurate "Door-to-Door" ETA instead of just a "Rolling Engine" ETA.

A dual ETA toggle ("Riding Time" vs. "Real Door-to-Door Arrival") would make Waze the undisputed leader in motorcycle touring navigation.
