Stopping Distance Estimator

Simple physics-based estimate for total stopping distance (reaction + braking). Adjust reaction time and deceleration to match conditions.

Dry pavement might be higher; wet/ice lower.
Disclaimer: Estimates only. Real stopping distance depends on brakes, tires, load, grade, perception time, and road conditions.
