This just repeats and expands what I said about it earlier, it seems to fire at just the wrong time.
Over the last week I've had it fire two or three more times. I think that each time, my foot was off the gas and headed for the brake, when the warning beeps began. In no case was I about to mash the brake, but simply slow down a bit to maintain clearance or initiate a small turn. If it had been critical, the mental time to process the beep and start to move my foot would not have been sufficient. In fact, it is DISTRACTING when it fires at just the wrong time like this.
Now, as I've said before, maybe this is the cost of having it fire when I really DO need it - but it seems it is going to be too late in that case.
I'd suggest something like making it more sensitive and giving a pre-warning, perhaps a simple yellow light, about a second earlier than present, and then making the real warning about a tenth of a second later - and optionally letting it apply a 10% automatic braking as well.
I guess they'd have to add a radar or sonar or something more precise before ever letting it apply 100% braking, I don't think the current warning system can accurately judge an imminent collision and panic situation.
One scenario seems to be when you're in city traffic at 30mph or so, and you start to close on the car ahead, which is still moving. Your closing speed is only about 2mph, and suddenly the collision warning is acting like a tailgate warning, which is a different thing. There's a LOT of tailgating going on in such urban situations, I can have more spacing in front of me than anyone else in sight, and then this silly buzzer goes off? And if you allow more space it invites lane changers to cut in and eat the space, which is I guess why everyone tailgates.
