Why reaction time = stopping distance
At 28 MPH, your e-bike covers 41 feet every second. Reaction time is the pure delay before your brakes even start working — the physics of slowing down happens after that. A distracted rider with a 1-second delay loses a full 41 feet on top of the ~50 feet it takes to brake. That's more than 90 feet — nearly a third of a football field — to stop.
