Advanced Driver-Assistance Systems

How well does it work when the road lane markings have been painted over with black paint due to changes in the road (for example, extra lanes added / removed) and you are driving at night or in rainy weather...?

It just ignores the black painted options.

Haven't really had any issues in rain...even I was surprised as I expected that to be a bit hit and miss.

I have had issues in extreme wind (and rain) though where it would eventually just pop up on the screen and tell you that it's turning it off.

There's definitely a threshold where it decides you are intentionally doing it and stops trying to correct, when say you are driving right down the middle of a solid line.

But in every car I've driven that has these systems it's always pretty subtle and it's not like it takes control of the vehicle it just adds a bit of resistance to the wheel.

It also looks for both lines on either side otherwise it ignores it, hence "lane" assist.

I had the Volvo XC40, and it was terrible. Would often get confused in wet weather with dodgy markings, but it’s at its worst in low speed driving in the estate and so on. A badly place cateye in the road would have it fully activate the emergency braking. Trying to reverse into a tight space would drive it nuts applying the brakes all the time when I don’t want it to etc. one would need to turn the rear collision assist off every time you wanted to reverse into a parking space, otherwise it would stop dead and annoy the devil out of you.

I hated that car

Our roads are not quite to a decent standard anymore with all sorts of cambers and bumps pushing the car around.
These help without you needing to constantly correct the car bouncing off or following these cambers not necessarily just keeping it in the lines. Just less work to do and as a result less mental energy to drive.

I think anyone who would not find these systems intrusive cannot be a good driver. The thought of the car pushing back, against what I'm instructing it to do, alone drives me dilly - much less it actually happening while I'm driving.

You missed where I said “in order” … Lane Keep Assist is helpful to be active in the event where the driver is distracted and doesn’t notice they’re crossing into the oncoming lane, in the same way that AEB will save your bacon by braking when you don’t see the car in front of you is doing that.

I listed it lower down because the other functions are just more crucial, but the basic principle should be that anything which can protect you proactively from getting into an accident is a good idea and worth leaving enabled (I put up with a LOT of Lane Keep beeping just so that it’s there the one time I lose focus and that will hopefully save me).

Except are you not training yourself to ignore all these beeps, up to and including the onetime it is useful?

I think it really depends on what kind of drive you are doing.

When I'm just doing the boring A-B stuff especially with lots of traffic I put it into full on traffic assist mode and let it do the work.

But If I'm hitting a nice mountain pass on a spirited drive then I just swipe down and turn it off so I have full control.

Also, we have to think of the "every man" concept and those idiots who literally can't find a lane by themselves and have their mirrors hanging over the painted lines....I would gladly suffer forced lane assist on all cars knowing we'll see less and less of that over time.

As a person on a motorcycle more of than not, Blind Spot Monitoring has been life changing from a safety perspective and I would like to think lane keep assist has also freed up the road for us somewhat.

Drive from home to my son's school, then to pta cbd (highway) then home in the afternoon (highway). All in all around around 40kms, 1 hour total for the weekdays

Odd trips on weekends so I should be good with all the tech 🤔

Nope, it’s not possible to ignore: you get the beep, coupled with firm steering correction from the car (which you can still override if you’re actively steering). My car is “helpful” and steers away from a curve as you enter a corner to help keep you centered, so you get used to the system pretty quickly. And you also don’t cross any lines without a flicker going, so the beeps and steering arguably make you a more accurate driver.

Bro, have you driven in Johannesburg before? Every second car is crossing the middle lane. I don’t know if they have really kak judgement in their bakkies and large SUVs, but we definitely need more Lane Keep Assist going bos to get people to actually drive neatly within their lanes.

Firm steering correction? - exactly what would drive me mad!

Well, to quote the other guy, if you’re not crossing the line, it won’t be an issue now will it? You’d never get to feel it.

Not that I know about it personally, but it starts before you cross the line, doesn't it? And didn't you just say you endure loads of unnecessary beeping yourself? Which, reading further, also comes with the car moving the steering wheel itself?

But each to their own; I just dont know how so many people suddenly dont know how to drive straight, or keep between the lines

It steers away from a line before you cross it, unless you have an indicator applied in that direction. It only beeps if you cross a line with no indicator.

If I had to guess why, I’d say a lot of people don’t know where the left side of their vehicle is, so they drive hugging the centre line because they can see that. Which gives them no room for error, so crossing into oncoming traffic and weaving back into their lane is literally all they do on narrow urban streets.

All you need to do is go to your local mall on any weekend & watch how some drivers fail miserably to park their vehicles correctly between the parking bay lines (or reverse park into the bays) to judge just how poor their situational awareness & judgment of their vehicle's actual size & position is, in order to realise that this same deficiency will also translate into how they also cannot keep their vehicle located accurately between the lane markings when driving on the highways & byways as well...

Here's a representative sample of 'bad parking' pics I have taken over the last half-decade or so in Gauteng & the Eastern Cape...

Reliability-wise, these systems are, in my experience, super reliable. No moving parts. I had a windscreen replaced once, and it did take a week or so for the radar stuff to re-calibrate itself (but could have been done by the windscreen people).
