The Actuarial Science Behind Usage-Based Insurance (UBI)
Traditional auto insurance rating relies on demographic proxies: your age, gender, credit score, ZIP code, and vehicle make. Telematics and Usage-Based Insurance (UBI) replace proxy underwriting with real-time empirical driving data collected via smartphone sensors or OBD-II hardware devices.
1. Why Hard Braking Is the #1 Telematics Risk Factor
Actuarial claims data indicates that drivers who frequently brake at rates exceeding 7 miles per hour per second are statistically five times more likely to be involved in a rear-end collision. Insurers consider hard braking a direct indicator of tailgating and delayed driver reaction time.
2. The Midnight to 4 AM Deadzone
Driving between midnight and 4 AM carries the highest statistical fatality and severe collision rate due to alcohol impairment, driver fatigue, and low visibility. Logging heavy mileage during these hours severely lowers your UBI driver score regardless of how smoothly you brake.

Frequently Asked Questions
Can passengers trigger phone distraction penalties?
Yes. Smartphone-based telematics apps cannot distinguish whether the driver or passenger is using the phone. Most apps allow you to manually categorize a trip as 'Passenger' within 14 days to preserve your score.
Are my driving behavior inputs logged on a server?
Never. All calculations, chart animations, and risk simulations execute 100% locally in your device's browser memory (RAM).
