I'll be honest, that braking assist has saved me from a couple parking lot dings. That's worth something.

The problem is I drive in a city with really narrow roads and it triggers the collision warning all over the place. I've also had it slam the brakes in a situation where that was not a good idea at all.

The forward attention warning ("you should take a break") is another one I'd love to be able to tune. I have a lot of late nights at work, falling asleep or becoming distracted while driving is a very real hazard that I appreciate, but it's absurdly sensitive.
