The system is working as intended though, so it's not technically a design flaw.
Just because it is operating as intended (I don't think it is) doesn't mean it isn't a design flaw. This just means it feels into the "unintended consequences" category.

I've had several things occur with the adaptive cruise control that I think are flaws. The truck sees a car stopped in another lane but can't determine it isn't in your lane and slams on the brakes. Or when a car safely crosses traffic in front of you but the truck can't determine what is really going on and slams on the brakes. These are working as intended but are poorly designed because the algorithms used can't anticipate or fully understand the whole situation.

What you are describing is not design flaw but consequences of the systems limitations. Design flaws are like the running board extended timer option that does exist and when you click it nothing happens. It’s a design flaw, it was designed to operate a set way but fails to perform its design intention.

The adaptive control not acting the way you prefer is not the same as it not operating as it is designed.
Also in the manual, it again lays out situations just like you said where the system has known limitations.

Just because it operates as designed doesn't mean that it was a good design. I think of a design flaw as something that doesn't work in an appropriate manner regardless of if it was intentionally designed that way and is just a bad design or if it was designed properly but isn't functioning properly.

Do these happen with BlueCruise engaged? I regularly have cars change lanes too closely in front of me on the freeway, @65-75mph traffic flow, and BlueCruise just adjusts for the now-shorter distance from the car in front, but never slams on the brakes or applies them too heavily.

I remember to try to set the cruise in traffic today Pressing the cruise ON sets it to 20kmh when stopped behind a car. When I release the brake it brings up the message "stopped" and then auto holds the brakes (I don't have auto hold turned on). When the car in front starts to move it shows the resume button symbol. It won't start to role on its own.
If you look at the video I posted, it shows the stopped no then flashes hit resume but then it starts going without me hitting resume.

I don't have BlueCruise but what you describe happens with mine as well using adaptive cruise on the highway. The slamming of the brake is usually just around town when a car is turning left in front of me or when the car in front of me gets into a turn lane but I'm going straight.

I don’t have the blue cruse but I have the level below. It operates like you said. Never slams the breaks unless the person is so close you would also.
It’s usually pretty good.
