The reason/cause of center lock wheels coming loose is a bit more complex than the simple inertial forces that you guys have described above and varies with spline drive/pin drive and female(rudge)nuts or the more common male nut(most alloy wheels as fitted to Cobra-GT40). The MALE type nut rule is; LH thread/LH side-- RH thread/ RH side. Braking/Acceleration have nothing to do with it.
What really happens is a form of epicyclic gear action between hub and nut if any loosness at all occurs and the weight of the vehicle is concentrated on the lower half of the nut/wheel contact area while in motion.
