I keep my collision warning (AKA Automatic Emergency Braking-AEB) at max just to be conservative. So I tend to get a fair amount of false alarms. I don't mind it because I want to be safe. I tend to get them when the person in front of me is slowing for a light or a car and I am just about to tap the brakes. I am almost always in regen, I think. Beep beep beep! And I think, I know, I know! I don't tailgate at all (anymore!). Today I was travelling down a good slope, with regen. The car in front of me slowed much more than I expected for somebody turning. The sun was in my eyes and I suddenly realized that he was stopping for a turn, not just slowing. I had just instinctively put my foot on the brake to slow more before realizing this was happening. I then slammed them on, locked the brakes for perhaps 2 ft and all was fine, fortunately. But normally the AEB goes crazy when I am farther away. I wonder if AEB does not work when the foot is on the brake. That concerns me. A light braking is much different than a firm braking. I would think that AEB would be active and vigilant regardless of whether I am braking or not and would be ready to increase braking to avoid the accident even if I were braking. The car was unfazed. And then, to add insult, one minute later I was slowing on regen for a stop with a car in front of me the damn thing went off when I had more than enough room for a slow and steady stop. Oddly, just this morning I was thinking that it was confidence inspiring to have the car be so sensitive to the approach rate to a car in front of me. Now I have lost that. Fortunately, I live in an area where this is actually the first time that I have had to slam my brakes on in my MS in 19 months. They worked like a charm. Not even a shudder. I'll share this ServiceNA.
