At 45mph the car is traveling at 66 feet per second, so 1 second before impact means it was spotted at approx. distance of 66 feet. The volvo XC90 breaking distance at 62mph is 112 feet. Dividing by the square of the speeds gives us a 45mph stopping distance ~62 feet. So not only would it have saved her life, it could possibly have prevented the car even touching her. (The XC90 has excellent breaking, btw, better than a range rover sport or an audi Q9).
