60 kW isn't hard braking -- that's the normal level you get in a model S when you take your foot off the accelerator anywhere above 20 mph. So coming to an anticipated red light, you'd normally brake at the full 60 kW tapering down to zero at about 10 mph, then use the mechanical brake. That's makes for a comfortable stop and wastes the minimum power. Hard braking, like slamming them on at 80 mph, can exceed 1000 kW.
