anyone has their SCBS activated before? i tried a few times where i'm danger close to a car in front of me and SCBS doesn't activate, it was so close that i almost cannot see the rear bumper of the car already, but of course i was able to hit the brake so no collision happened

i tried before under 30 km/h and under 25 km/h and the SCBS doesn't activate at all

and while driving i noticed some strange behavior with the car, not sure it is normal or not
- when i'm coasting slowly and once the speed dropped to 30km/h or lower, i can feel the car is trying to stop itself, is like changing from 2nd gear to 1st gear similar to engine braking

- when i press the brake pedal, i can hear some hydraulic hissing sound and when i try to press the brake pedal 100% i can feel there are some stopping point in the middle, the action is not smooth

is this 2 behavior an intended design?

You all make me tempted to bang the smart tag toll gate to test out SCBS already

Usually no.

Why do you need it?

Unless you want to do used oil analysis....
