@Jetliner ACC definitely feels like its in its infancy as a technology, like if cruise just locked the throttle at whatever percentage of max you had it at instead of giving more or less to maintain a target speed.
ACC is currently (as far as i can tell) only using instantaneous position/distance to set the target speed so when you get cut off or someone jumps in that gap because people drive with cat logic (if i fits, i sits) it will notice the distance collapsed and set its new target like 20-30mph lower for this distance and start braking.
What it needs to do is at a bare minimum take the derivative of the position data, smooth it slightly because dervitives amplify noise, and then use this relative speed to determine if it really needs to slow down. (It could also just find out exactly the speed the other car is going and make that its target if that speed is lower than yours while trending towards the desired follow distance.)
As far as lane sense and blind spot monitoring, go to setting and disable the chime, i only have it on for long road trips where fatigue is a concern. And lane sense is similarly poorly implimented with it just turning the wheel a fixed amount instead of dynamically inreasing it to keep on its side of the line, i leave mine off since it isn't actually able to do its job. (At best the wheel turning is an alert you drifted, amt worst it actively fights you)
I think the real leason here that can be applied to self driving cars are that programmers apparently don't drive or many of these issues wouldn't be a thing because its common sense that cruise isn't just lock the throttle at 45% because that only works on perfectly level ground with 0 weather.
Overall these technologies are a net positive even in their current form, but that doesn't mean they are perfect yet. (I still wish other drivers would just use normal cruise, let alone the fancier assist features)
