My 2015 would have the 'collision alert' because a car was in an adjacent turn lane, but the road curved and it didn't know that.
It also would go off most days on a stretch of road because it was certain I was going to slam into the guardrail of the curve. Again, the system had no cameras, no map awareness, so it just had radar saying 'something metal ahead'.
It was slightly annoying but left it on, just in case.
Now my 2023 on the other hand hasn't had a false positive that I can recall, in fact if not for one incident, I wouldn't even know it was doing anything. Someone pulled right out in front of my kid learning to drive. I had just enough time to think "oh, we are going to hit or my kid is going to yank this thing off the road". Instead, my kid executed a shockingly perfect evasive swerve that landed perfectly into the free lane. Then I find out that it also would take over steering and as a result, I'm pretty certain it saved me a pretty significant wreck.
