Shared scooter batteries die mid-trip with no accurate range display

Shared e-scooter apps show battery level as a rough percentage or 3-bar icon, but this estimate is wildly inaccurate because it doesn't account for rider weight, hill grade, headwind, or cold weather. So what? Riders pick up a scooter showing '40% battery,' plan a 2-mile trip, and the scooter dies on a 6% grade hill after 0.8 miles. So what? They're now stranded in an unfamiliar area, still being charged per-minute on some platforms, with no way to complete their trip. So what? They have to walk the remaining distance and are late to wherever they were going, destroying trust in scooters as reliable transportation. So what? People revert to cars for any trip where arriving on time matters, which is most trips, making scooters a toy rather than a transport mode. This persists because operators optimize for fleet utilization (deploying as many scooters as possible) rather than per-unit reliability. Accurate range estimation requires per-vehicle calibration with load cells and IMU data that current $300-400 scooter hardware doesn't include.
