I have never understood how this would work in the real world. If my car automatically brakes, I would just get cutoff by other drivers constantly until my car comes to a complete stop in the roadway.

And yet I have it in my very real world (and unexciting) Subaru for years and it never does what you say. I’m guessing it has some idea of differential speeds , not just distance-to-object

You're thinking of adaptive cruise control. Automatic breaking only activates when you're about to crash.

This almost got me into a serious accident, twice. Definitely would not recommend and I switched cars because of it. The last thing I need is buggy software with the capability of instantly changing the trajectory of my vehicle (slippery surfaces, cornering). A brand car as well (MB) so really, really disappointed, what should have been a safety feature actually was the opposite. Dealer said everything was fine so that was the end of that car, if 'fine' means that you have a couple of close calls in the first few thousand km on account of a feature that can't even be properly disabled without sabotaging the electronics then that's just too bad.

Now I drive a 27 year old car that has none of these 'features'. It does what I tell it to and when I tell it to, it doesn't phone home, and has no touch screen, but old fashioned buttons.

If the government wants to immediately improve car safety they should outlaw touchscreens instead.

Yes, because the automatic braking 'feature' can cause you to crash.

I too have a Subaru, my emergency brake has only engaged when trying to parallel park a bit too aggressively. I must be a very good driver! But perhaps it has saved my bumper a few dents

so if someone merges over into your lane where you are it doesn't activate? I must not understand the point of this feature then.

I've had a car that apparently has "automatically breaks" because the darn thing spent more time in the shop than on the road.
