Lane Keeping danger

[Marc Wester]

Hello Everyone!
I am a new 2025 Taycan 4S owner. One issue I have is with the lane keeping which turns on when you start the car even if you turned it off previously. In France, the roads can be narrow requiring you to move to the right edge to allow oncoming traffic to pass. The lane keeping will pull the wheel back into oncoming traffic which is quite dangerous if you don't expect it. Is there a way to disable this permanently?

No, it's forbidden by regulations to turn it off permanently.
And it's on every car sold in EU. The only difference is how hard the manufacturers make it to disable.
On the Hyundai it's a long press on a button on the steering wheel, so it can be controlled easily, even while manoeuvring.

You can’t turn it off permanently, but you can hold the button on the cruise control stalk to turn it off for that drive.

I have always had that features on all my cars (including taycan). It’s has always been very easy to ignore its self corrections. Not sure what’s the problem… or do you drive with only one hand on narrow roads?

Maybe the intensity was increased with the MY25?
My Honda is very subtle while the Hyundai was quite hard to counter.

"New rules around active safety features in new cars, which include ‘speed limiters’, come into effect from Sunday (July 7).

The EU’s ‘New Vehicle General Safety Regulation’, also known as GSR2 or Regulation (EU) 2019/2144, amends the minimum performance standards (known as type approval) for motor vehicles in the EU, adding new required Advanced Driver Assistance Systems (ADAS).

These include Intelligent Speed Assist (ISA), Autonomous Emergency Braking (AEB), Driver Drowsiness and Attention Warning (DDAW), and Emergency Lane Keeping Systems (ELKS)."

&

"Can you turn it off? 
It can be switched off but GSR2 requirements mandate that the feature is reenabled - automatically switched back on - every time the car is started."

I believe using indicators before changing lanes defeats it If no other traffic is present in the adjacent lane
it is very disconcerting. Particularly in Road works where there are new and old lines visible - it gets very confused.
Innodrive Cruise Control suddenly increasing speed.is another risk.

Slightly off topic - but I have been waiting for someone (eu/uk) with a new car to comment on the ISA and how much that interferes.

It is meant to keep cutting in every time you exceed the speed limit and I'm surprised nobody has commented yet (even on a test drive).

Depending on how well it is / isn't implemented, it may affect my choice of next car. Ie buy a pre 07/24 car.

Back on topic - I don't really like the LKA and have it turned off. Annoying if you also need to turn it off every journey now.

I had it on a loaner. Three bleeps when you exceed. I think it is the same sound for not wearing seat belts, but only for 2-3 seconds. Nothing to worry about.

The first thing my dealer did as he was showing me the features of my new 4S is program the steering wheel button to turn off the ISA.

Passive safety features, even if they’re annoying, is one thing but a safety feature that actively changes the car direction needs to be perfect and the LKA is definitely not perfect.

Not many MY25 cars out there if this is a new EU regulated mandated feature. All manufacturers will be forced to implement.

Might be that you can configure Individual drive mode to disable this setting amongst other things - requires Sports Chrono to be present.

If so, then no real hassle.

That's good to know.
I know it's not mandated for the UK - but we will get it, in tandem with EU cars.
The concern was manufacturers going for the most intrusive option:

Manufacturers can fit cars with four different ISA systems (sound warnings, vibration warnings, feedback through the accelerator pedal or a direct speed control function), which are intended to prevent the driver from exceeding the detected speed limit. Regardless of the system chosen by the manufacturer, the new law states that it must activate automatically each time you start your car and can’t be permanently deactivated.

If your car’s ISA system is set to automatically limit the speed you travel at, you'll be able to temporarily deactivate it by pressing hard on the accelerator, but it will be reactivated every time you start your car.

I am all for systems that genuinely improve road safety. But not ones that interfere, but don't achieve their objective.....

I'm actually more concerned with uninsured teens flying round on electric bikes / scooters wearing balaclavas and OAPs who are obviously blind dawdling along at 30mph in a 60mph limit - than a sensible driver doing 75mph on the motorway.

Sorry.... Off topic rant ?

yes, with PIWIS

My 4S occasionally gets the speed limit wrong. it appears to read road signs rather than using GPS. So I find it occasionally picks up the posted limit for a side road if the sign is badly placed or miss a correct sign obscured by, say, a lorry.

One further worry is they might retrofit the ISA system via an over the air update.
