Try this... measure braking-distance from 45mph to 0. Then measure how much distance you need to accelerate from 0-45mph and you'll see the vastly different forces on the wheels in power-transmission versus braking. You can also calculate the difference in hub wind-up as well. Problem with such large torques on the hub in radial-lacing is that you end up really wearing out the spoke-holes. And if you have single-sided discs, you end up twisting the hub-center because the left & right flanges will face vastly different torques under braking.
As for your 2nd point, there's really no advantage to radial spokes over half-radial. Just that there's no really any disadvantages either, aside from hub-flange durability.
