[QUOTE=sgkent;1445401]I do not have CMBS on my 2015 MDX, only the brake collision warning. Based on my experience with it lately I would not want the full CMBS. My system is set to the normal level of warning, and it goes off all the time telling me to brake. This can come when I am already braking at a light behind someone, in a turn where it sees a high curb as an obstruction, once where there was a suddenly light change - it sensed the change of light to shade as an object. This is a daily occurrence for me. Ironically when someone ran a red light and hit my 2014 almost head on (totaling it), the warning didn't even come up until they were almost in the collision - while my mind had already begun to take evasive action, the system had no clue. All that said, the smartest guy as to AI was interviewed a few weeks ago about the Tesla collision and he said to paraphase, that these systems are not at a state of deployment where they can make the decisions for us. They are only driving aids - that real AI in driving that can be fully trusted won't happen in our lifetimes. It is a generation or more away. So, while I accept the warnings, I would not want it slamming on my brakes where someone else will rear end me. Based on how people drive here one is more likely to get hit by someone from behind. I have the lane departure off because I got tired of what seemed like constant warnings at changes in the color of the pavement, or hedges angling towards the road, changes in road width. Each person has to decide for themselves on how they want to drive. If you turn it off and miss that someone has stepped in front of you, you will feel bad also. That said see this video of the gal who was hit by the self-driving Uber car.
I have a 2018 Hybrid Advance, and I don't know if there are differences in the CMBS between that and your 2015, but there are some anomalies in what you are describing. If you are already on the brakes, the first two levels of the system (as described in an earlier post) should not activate unless your distance is close and closing speed is high; the system radar should not respond to a curb, unless it is a very, very, high curb; the system should not respond to shadows, which provide no reflectivity to radar; and (to respond to a different post), the lane departure warning is camera based and the camera needs to be able to see lane lines to give a warning. I would suggest having the radar unit checked for function and alignment and cleanliness of the radome, and, for the other post, checking the alignment of the camera and any dirt on the windshield that might be interfering with its function. In my 2018, I have found the CMBS and LDW both excellent. (And IIHS has given the CMBS a "Superior" rating.) The LKAS is also excellent in my experience. And yes, these are "driver assist" systems, not autopilots, but in the 2018 at least, I find their function very useful. There is a reason that Acura calls the CMBS a mitigation system rather than a "prevention" system. If drivers think they can do better without such assist systems, the fatality and permanent injury figures suggest they're wrong.
