I don't think it's magic, but: 1) Stopping distances go up as the square of speed, so 40mph has huge advantages over, say 70mph. 2) Survivability of accidents

I don't think it's magic, but:
1) Stopping distances go up as the square of speed, so 40mph has huge advantages over, say 70mph.
2) Survivability of accidents at 30-40 are way higher 70 (unless pedestrians are involved, in which case 30-40 is already too high.)
3) Radars and Lidars really can't see/classify things very well at the distances required to do comfortably stop for obstacles at highway speeds.
