25mph is 36 feet per second, about the length of a school bus. The stopping distance at 25mph is 30 feet, assuming perfect reaction time and dry pavement. Human reaction time is about 750ms, so stopping distance is about 2 school bus lengths. You don't have seconds.
25mph is too fast for any street where kids may jump out behind parked cars. Not just school zones, but all residential streets. There's a knee at about 20mph in the traffic fatality stats where below that speed pedestrian collisions are unlikely to be fatal. Above 20mph fatalities become more common quite quickly.
