I can answer this, since I have a new car with this camera and polarized sunglasses.

MOST of the time it's good about telling when I'm looking and when I'm not, out of maybe... 5 alerts over the previous 8 months all, but one occurred when I was in fact looking away for one reason or another. Likewise when it's correct my lane-keeping it's been right about me drifting.

Given how inattentive I see other drivers being, on their phones for example, and taking into account that I'm (based on my record) a good driver who is attentive... I appreciate these additions. I doubt that they make us less safe, we just dislike anyone or anything telling us how to drive, because "we already know what we're doing." The subjective experience of being distracted however isn't usually so clear-cut, it FEELS like you're paying attention.

Note: This is a new model Lexus, so I expect this represents that brand as well as Toyota, but beyond that I don't know.

Just because it's available in a Lexus does not mean it's available in a Corolla

		In Europe it does. ADDW is required in all new vehicles, including Corollas.

There is no way that training people not to worry is making us all safer. I don't even like how new cars have this thing where they will automatically hold the brake once stopped even if you let go. There is no way it's a net good to train people that running cars just stay where you put them like an inert object does.

		The result for me has been pretty predictable, I'm getting a kind of corrective feedback so I drive in a way that prevents that feedback. The practical result is that imo I'm a better driver, I'm more aware of my lapses in attention, my tendency to overcorrect to the right, and so on. I'm yet to experience a downside, this isn't like using "Autopilot" or some other situation where a machine is taking over for me. I don't see why our skills or caution would be lessened by exposure to realtime feedback.
