How does the collision detection work as I have had it alert me a couple of times but when i try and test it , i.e. brake at last minute nothing goes of and If I hadn't of braked by then,then I can't see how the car would have stopped me in time when it does come into action.
I have it set on the 3 bars so most sensitive but worry if its actually working properly .
