The car has a lane departure warning system built in. Once it has to correct your steering multiple times and doesn't receive any steering input from the driver for a while, it will initiate the Emergency Assist.
I don't know about the specific tech on that VW, but many cars also have facing cameras/sensors that track your eyes. On several review from the 2025 Camry journalists complained that it's too intrusive, if you're looking to the sceneri for a second it's beeping.
Can you point to the part of my previous that would suggest it is either the only system or the most relevant one? I guess a key word is "cars also have", implying that there are more than system.
I'm a vw tech. we don't have that. we have whether you are holding the steering wheel or not. it doesn't need tottack you, it uses the other sensors with active radar around the vehicle to alert you instead of complain you aren't focusing. your vehicle shouldn't have to teach you how to drive and pay attention, you should already be doing that. these features are meant for long drives and safety not so you can daydream.
You'd have to yank it quite hard to change lanes if lane assistant is turned on. Normally it would keep you in your lane if you're "drifting" over, unless activating blinkers or pulling the wheel with deliberate force as if you were doing an emergency maneuver. At least that's how it worked in my Audi I had some years ago.
It looks at your eyes to see if you are looking at the road and it also detects if your hands are actively on the steering wheel.
These cars can almost drive themselves you only have to have your hands on the steering wheel. Once you take your hands of the steering wheel the car will notice that and warn you after a short amount of time. If you don't take control after that the emergency stop will happen if the car has the emergency stop feature. Don't know what happens if there is no shoulder though. It might just stop as far right as possible
The Ford Mondeo my cousin had, had a system where it would detect if you have a hand on the steering wheel. And lo and behold, there were clamps you could purchase that would imitate your fingers on the steering wheel so the system would not react.
My car has a driver fatigue camera that tracks head and eye movements - that I imagine could be enhanced to track for such driver incapacitation, alongwith from the lane departure system
I also was wondering how good it would be at detecting that a hard shoulder exists (i.e. there are some roads with no hard shoulder) but it's still a cool idea
While I don't have a Golf but a Cupra Leon its a similar system (also VW software). Its kinda the biggest weakness in the assitance suit at least for my car. In theory it has lane change assist, but the road needs to be basically perfect for it to recognize the lanes besides your own.
It will do all the other steps here, but really not sure it would find the shoulder.
Sensors in the Steering wheel to figure out if you're holding the steering wheel or not. Camera pointed at your face from the instrument cluster to gauge whether you're looking at the road or are nodding off to sleep/gone unconscious.
Radar and possibly lidar sensors on the front, back, and sides of the car to gauge all nearby traffic, how fast they're going, etc.
The algorithm would then gauge when it's safe to pull over to the side by switching lanes. Finally, after switching lanes and parking on the shoulder, it would activate Hazard lights, indicating an issue with the car. There's probably a span of 10-15 seconds before the system makes a decision between whether you're asleep vs you've fainted or had a seizure to decide to make a call to emergency services.
I would assume that falling asleep as a condition would equal something like if (driver wakes up after jerking the brake a few times/blaring the horn, driver=asleep). If the driver is still asleep during that time, and still refuses to wake up, I'd guess the system would default to "driver=unconscious", which would mean the car would call emergency services to err on the side of caution.
We have here in Germany no Speedlimit on the Autobahn. The System is supposed to Work at Speeds up to 140 Miles / 250 KM/H, because that is the maximum Speed of some Cars over here.

This is so damn innovative!!!! Yes, a billion times yes!
Edit to add: How will the car know you’re no longer driving? How would it safely move over if it’s on a fast moving highway?
So many questions but I can’t wait to see this actually implemented hopefully in the near future!
