Helicopters? what about Speed Bikes?

Hello, well more of what you don't want I suppose!!just a topic as this is what it is for.Who is doing all the speeding along Ash Close in little ?cc bykes, it really worries me in case a child should run out from the School entrance by the Church, I know it is holidays but 'anywhere' for that matter!, perhaps the noise is more than the speed actually is, but could they STOP if such a child did actually run out?
