I find I'm using TACC less and less since it keeps braking and beeping at me as I steer around cars parked on the left hand side of the road. It needs to get better at identifying potential collisions (or more specifically, when the current trajectory is close but not going to hit the car) before I'm confident with using it. Occasionally I'm not ready for those cars on the side of the road and it slams on the brakes, despite the fact that I am easily going to clear it. It's just not clever enough yet. Likewise people that drive across in front of you. They don't stop, but the TACC tries to, and panics. My other half won't use cruise at all. The bong is my friend to be honest. I've been using cruise on city streets for years. But my previous cruise wasn't as clever as TACC, so it didn't brake for things I'm not going to hit!
