Hey everyone, I've been using DAPP during my highway commute, especially in stop-and-go traffic. While the lane centering is ok, I'm struggling to trust the braking.

Often when the car in front stops, I feel like my car isn't slowing down fast enough. It gets so close that I usually freak out and slam the brakes myself to avoid a rear-end collision. Even in hands-free mode, I’m constantly hovering my foot over the pedal because I'm nervous it won't stop in time.

Is this just how the system is tuned, or should I be worried? Has anyone actually had it fail to stop, or am I just being paranoid? Also, does changing the following distance make it start braking earlier, or does it just change the gap?
Would appreciate any feedback, thanks!
