Yeah, I have a recent Subaru with those features. It beeps when I'm backing out of the garage and there's someone driving or biking up the road before they even come into my sight lines.

It can help keep me in a lane, either by beeping or nudging the steering wheel if I drift - I only turn on active lane assist on long highway stretches, it is more of a security blanket than anything else - just in case I space out for a sec, here's another layer of defense.

Adaptive cruise is also great. Between the two, in long road trips I can put the car in a travel lane and just go. I still have to attend to my surroundings, but it is a lot easier to focus on that when I'm not worried about accidentally creeping up to 90 mph because suddenly there's nobody in front of me.

I also had the auto brake feature activate once when a car in front of me stopped unexpectedly. I was in the middle of braking, but the brake pedal depressed further and there was a loud alarm beep.

None of these are autopilot, and honestly I wouldn't want autopilot until it is legit reliable. Instead, these are defense in depth features. The computer helps prevent certain mistakes as I make them, but never is in primary control of the vehicle.

Subaru's system is simply fantastic and you can tell they thought a lot about the "human condition" (human weaknesses) while designing it.

Lame keep assist is very subtle, I describe it like wind blowing on the side of the car. You can trivially over-power it and it will beep if you exit the lane (without blinker on) with or without lane keep assist active.

The whole package of safety features is wonderful and impressive for something starting at around $22K.

I drive a Nissan myself, but from the sounds of it it's about the same. LDW (just warning in my case), FEB + pedestrian/moving object detection, blind spot detection, intelligent/adaptive cruise control. (There's also a lane keeping system option called ProPilot, but I skipped out on that - I don't think I'd trust it in the regular rain anyway)

Anyway, my point is these things are common now, and while getting the full package might cost a premium, the more important parts (like FEB) are certainly becoming fairly standard.

From what I understand, Subaru develops their own. They are the only ones where there are two cameras in the front that both see in color.

We have a 2017 Subaru with all of these and it's really excellent.

I have ProPilot. It's pretty great. In heavy rain it shuts itself off and tells you that it is unavailable in bad weather.

That's great news. ProPilot sounds ideal for dealing with daily stop and go commute without the cost and risk of Tesla
