Sometimes technology sucks!

It has a system that detects when you wander out of the lane you're in, or onto the hard shoulder, and the steering wheel moves on its own to correct your trajectory.

I hate it ! It makes me jump when the steering wheel moves without me turning it.

In my opinion that is dangerous.

If it is surprising you when the lane guidance intervenes, that could be taken to imply you are driving without due care and attention. Arguably it is your driving that is dangerous and proving that the system is needed. If you were driving correctly and maintaining correct road position, it would have no need to intervene...

The problem is the system can't differentiate between changing lanes and wandering !

As other's have already said, it knows the difference by correct use of the indicators before making a deliberate manoeuvre. (or do you perchance, drive a BMW?)

Rather than immediately doing down Joe's driving again you can read he's said that no, in his Peugeot the indicator and the Lane assistance are not linked. Which seems insane. But... y'know French electronics.

I only drive in the UK when I visit my Mum, which used to be every 3 months, before Covid.

I drive from Birmingham airport to Tamworth and back on the M42.

Will let you know the dates of my next visit so you can steer clear of me on the road

If we all get the correct cars, they will automatically steer clear of you.

Depends if he stays in lane or not...
