Yes, it can, but i must offer caution on who you employ to do ut fir you, as there's lots of clever software engineers (most of whom can't drive the product) in the industry I work in (truck design and manufacture) desperately trying to make that impossible. Under cover of cyber security, possibly, but they are probably more worried that people who didn't write the coding, fail to realise how it works fully and inadvertently remove something that makes the vehicle safe.

I foresee, insurance companies immediately impounding crashed vehicles, and paying the manufacturer to check the software level.

I hope you’re right, but I have a sinking feeling that a lot of this stuff will be beyond the reach of all but the most skilful tuners.

My backup option is to just stick some waterproof masking tape over the cameras and radar. You’ll get an error on the dash but at least it’ll kill these dangerous and accident inducing systems.

ISA required on all cars sold from July 2024, so if the hardware is not installed it must be installed before sale. That's what the law summaries say.

This is why I am maintaining a 2004 Subaru Impreza and 2011 Cayman. Both basic analogue cars and one doesn't even have traction control.

I like Lane Change Assist, it's just a blind spot warning, no steering inputs. It uses radar sensors mounted in the rear "bumper".

Lane Keep Assist is the one that adds steering inputs to maintain the lane. Absolutely loathe all of these systems. It uses a camera, but I don't know if that is the same one used for traffic sign recognition.

Genuinely dangerous imo on country lanes where it'll variously seek the hedge or oncoming traffic.
I guess it is one more step towards fully autonomous modes of transport.
All designed to fail with human input still being part of the equation so they can say it’ll only work when we have no input at all. Welcome to the future…

I had one of the new Cayennes for a while. Lane change assist and speed warning were on ALL the time. You had to turn them off.

Speed warning sounds great, but when you are in start stop traffic and you go 28mph, to 31mph, to 29mph, to 31mph it beeps every time. And I think lane change is dangerous, the whole correcting the steering thing is horrendous.

Volvo’s implementation is much less intrusive than that but it was amazing when a Porsche spun and crashed in front of us on a wet dual carriageway.

On its own the car tightened the seat belts, brakes very hard whilst simultaneously steering around the spinning Porsche and the larger bits of debris. I have little doubt that I couldn’t have done that. This was a 2020 Volvo.

The automatic magic speed limit following thing is annoying though, in our 2023 model you can turn it off and it stays off.

I doubt it.

Reverse engineering these increasingly complicated vehicle systems is becoming exponentially more difficult.
Huge numbers of computers in the car exchanging millions of messages over CAN. ;(
Protected ECU firmware, encryption etc etc

Maybe analog defeat methods might work.
Tape over the camera/sensors etc Unplug them etc?

Or they’ll engage the electric handbrake if the system input isn’t making sense ….
My 2018 car did this when I tried to hold the drivers door ajar to line-up my parking in a tight garage !

if disabled and you are involved in an accident, expect zero insurance cover.

'... if your car has a speed limiter, you disable it and you’re involved in an accident caused by excess speed, your insurer might refuse to pay out.''

...I would say 'might' would be 'will' as any excuse to not pay, they'll explore and take.

Many systems also use GPS to determine the speed limits for the ISA.

It can be switched off every time. The issue is that some manufacturers make it easier than others.

This… absolutely no doubt they will exercise the null & void and then the lawyers bills clock starts ticking..
