I used so little of the normal brakes that in the GTE the rear brake discs had to be replaced at around 9000 miles due to rust and pitting (because the GTE does not have auto brake-cleaning, and i rarely ever used the pads).
But yeah, Kezo is of course correct. As soon as you slow down, basically, the lights come on.
To put the 1.3² into a more palatable frame: if you drive 30mph (around 13.4m/s) and slow down at 1.3², you come to a stop after 10.3 seconds (or around 70m). That’s equivalent to very light to light brake pedal pressure in an ICE car (engine braking into lower gear is around 0.5²).
