On my 2018, they are far from perfect. On several occasions they flashed when I am already slowing down or worse, they flash and scare the crap out of me when a car is in the lane next to me. It is a good thing I do not have it set to break automatically, because that would be dangerous for the poor Prius behind me.
The manual says it will not brake for you, but it does pre-load the brakes.
