The regular false positives are so annoying that I sometimes fantasize about removing the camera, then remind myself that it's a leased vehicle and that I only have to endure it for ten more months. Some folks don't mind getting dinged at incessantly, but I have sympathy for people who dislike being constantly techno-nannied or notified to death.

Sticker in a strategic spot?

For me, missionary position is just fine

Is it because of the "older" tech? 2015 is "ancient" for these things and difference between 2015, 2020 and 2023 from what I've seen is pretty massive as tech has changed at a dizzying pace.

my 2020 civic seems to do okay but I get those issues only on occasion. Newer tech would be more stable I think. Only been driving it ~3 months.

I dunno. The first car I drove with any of these driver assists was my sister's 2015 Honda (CRV? I think that was the model). I thought it was fantastic. It kept station smoothly behind other cars. The lane-keeping was great on the freeway, and easy to turn off on surface streets. I thought it made me several times safer as a driver: I didn't spend as much attention on the lane markings, or the back of the car ahead of me, so I was able to be far more attentive to cars around, or upcoming (potential) hazards.

When we looked for a car a couple of years ago (and, more recently, when I've driven rentals), station-keeping was certainly no better (and in at least a couple of instances, definitely worse), and as noted by everyone else in this thread, the whole system is so darn annoying. Of the beeps and warnings which are not false-positives, most draw my attention to things I've already seen, so they become either distracting or ignored, which is a net safety degradation.

I think 2015 driver-assist systems (or Honda's, at least) worked better.
