Lane assist can be seen as a quality of life improvement, but wouldn’t auto braking be a purely safety feature, with 100% life saving potential ? Also 3 stars

Lane assist can be seen as a quality of life improvement, but wouldn’t auto braking be a purely safety feature, with 100% life saving potential ? Also 3 stars doesn’t look bad to me if you meet the bare minimum standard. I mean, it’s fine and people will look at the prices to compare anyway.

My car has lane assist but it makes life worse because it doesn't recognize how lanes are used in this country. In the countryside on certain roads you are supposed to cross over the dashed line so it just keeps dinging at you until you disable the system. Side assist flashes bright leds in your eyes whenever a car is in your deadspot which is all the time on the motorway. The car needs to tell you whenever the temperature crosses over 4c. It likes to warn you that the tire pressure has changed when it is absolutely fine when you test it. I suppose auto braking is the only one actually useful.

Only if the auto-braking works perfectly. If it ever auto-brakes when it shouldn't have there's a good chance of it causing more risk than if it hadn't been there at all.

  btw. aeb systems are basically working perfectly that they are mandatory in new cars in europe starting in 2022? (btw. lane-keeping assistance and warning of driver drowsiness are mandatory as well in 2022)

  I suspect that's what happened to my mother. She was caught in a pile-up when a car suddenly braked hard for no reason: straight line, no obstacles, full visibility. The front driver said (honestly or not) that he didn't understand why his car did that. The good news is that her passive safety systems worked fine and she came out unharmed except for minor burns and bruises caused by the airbag. I've also experienced unwanted braking in cars with an auto-brake system. Nether in a situation where it could be dangerous, thankfully, but it is clear that the system is not 100% reliable.

    Auto-braking systems only operate a low speeds (below 15mph I think). There’s also the emergency brake assist systems that do operate a speed. They use front facing radar to detect objects you might be about to collide with, and increase the brake pressure assistance, so you still need to physically press the brake. But if the car thinks you won’t stop in time, then it’ll multiply your break input to try and bring the car to a holt fast enough. But, you need to provide the initial brake input, they won’t fire alone.
