Automatic braking systems save lives. Now they’ll need to work at 62 MPH

Some of the complaints in this thread make me wonder if Mercedes has a really good automatic braking system, or if you are all much more erratic drivers than my wife and I to make them kick in all the time on your cars (or maybe a the systems are all temperamental, and we just happen to have driving styles that align with MB's AEB). Across a couple of their cars, I've only noticed it kicking in once, and in a situation where it definitely helped avoid an accident (car ahead braked rapidly and unexpectedly in fairly light traffic at around 40mph).

They have been recent cars though, so I'm inclined to agree with the comment theorizing that maybe those cars just aren't as new

Same, have never had a false positive in five years now on my prius prime (2019), and the times when it has engaged have been helpful.

We have a Toyota Sienna, and it's never had a false positive either. Once when it triggered, it definitely prevented an accident. The other time, I think I could have reacted quickly enough to prevent an accident.

I feel the same. I've put at several hundred miles each on four makers of cars with AEB through rentals and many tens of thousands on another two through long term ownership. I've probably had about four real AEB engagements I can remember over the last decade, all of them being pretty reasonable engagements.

I really do think that many people tailgate, approach slower cars too fast, and otherwise drive pretty unsafely and assuming they're driving just fine.

Could be the road conditions which vary by location.
