I'd not noticed that behaviour, but I had noticed that it can take a few seconds to return to full beam. I wonder if the system is waiting until the camera gets a clear view of the road ahead before it returns to full beam. 🤔

Other system behaviour has reinforced my view that the automation is configured for wide, straight roads. And indeed, there's a caveat to that effect in one part of the manual (the ProPilot section, iirc).

 

The auto-dimming feature is pretty poor, really, in comparison with a human driver. Far too slow to react generally. However, I tend to leave it on anyway, as a back-up, in case I am distracted.

 

I think it's deliberate. Some cars are too keen to go to full beam and end up blinding other drivers. I don't know how they get away with it.

 

That explains why it raises late but not why it dips late. To be fair, it’s an incredibly hard AI task to get it as good as an alert human driver so it doesn’t surprise me.

 

Wife's car does the same thing, have been used to my car that is multi zone dipping etc (creates a light tunnel) and it felt strange when the only time I've driven hers at night that it didn't come back on. The BMW is almost instant to dip/bright for the zones etc, so had got used to it.

 

I've also found problems with the auto dip, very poor reaction time. My previous car was a Focus, the auto dip/full beam was absolutely superb, in fact, two years ago when I bought the Leaf, had Ford produced an all electric car I would most certainly have gone for that.

Nothing has really changed in terms of UK sized cars.

 

I rarely use the auto feature so can’t comment, but my wife does regularly in her car and is a big fan. Never had it before so no comparison but she says it’s very reactive on narrow, twisty lanes. Reactive before and after a passing car.

 

Hi my nissan leaf has auto dimming on the headlights.
They work on straight roads pretty well.
As soon as you are going around a corner and it'd dipped down but until the stearing wheel goes back through the horizontal position it will not come back to full beam.
I could be going around a corner for ages but until you straighten up it will not come back on.
I had a courtesy leaf and it was the same.
so does Anyone know if this is a design fault or is this what'd ment to happen.
Thanks andy
Ps iam dyslexic so please don't just slag my question for bad grammar please.

My car was always like that (2019 Leaf) and I think it is how the software is programmed, the steering wheel has to be perfectly straight for a few seconds in order for high beam to come back on.
That's my first car with Auto High beam, I find it fairly OK in dry weather and fairly straight roads but on bends and hills and rainy weather, not so great, not dipping down on time or turning back on with a car oncoming in distance.
