G'day MyBB

I have been driving my Peugeot 2008 SUV for around 5 years now, and although it has served me well, i think it is time for something new.......

Is it worthwhile to go for a car that has all this new fangled systems as mentioned in thread title...... Spoke to a few people that say things like the new cruise control systems can be quite irritating etc

Thoughts please
 
The lane assist on most cars is a hit and miss since half the roads are not painted but agree on the radar assisted cruise control long trips on the highway over 100km/h definitely nice to have.
 
my GF toyota has lane assit and radar / distance speed cruise.

the radar / distance speed cruise is awesome - love using it

lane assit can be nice - I found it's best on long trips where there is clear visible painted lines on both side of the lane.
also I found in strong cross winds it battles a bit.
 
all the tech is nice, until it isnt and costs a fortune to fix when it breaks, needs dealer tools to diagnose whats wrong with it,
and needs specialized parts like windscreens as thats where the sensors are hidden.

thats is the problem with keeping such cars on the road long after the warranty has run out,
can an independent fix it? probably not,

and thats my problem with it,
 
In order of how crucial:
1) Blind Spot Monitor
2) Adaptive Cruise Control
3) Rear Cross-Traffic Alert
4) Lane-Keep Assist
5) Steering Assist

You’ll normally find auto emergency braking bundled in with Adaptive Cruise Control, but not all ACC is the same. Make sure you understand what the minimum speed is at which it deactivates, and how seamlessly you can reactivate it. Modern systems will work all the way down to a full stop, and then take off again with a confirmation press from you, so you get full cruise in stop-and-go traffic.

I personally keep Lane Keep Assist active (which beeps if I cross a line without indicating and will proactively apply some steering pressure to stay within my lane), but don’t bother with full steering (which I find to be too jerky and uncertain with our bad road markings).
 
Thanks..... so all and all. might as well get it, and decide what to use it seems
 
I test drove a car and the adaptive cruise control in the traffic was really great. No need to physically start and stop all the time. You just steer and have to worry about the robots. What a pleasure in traffic

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.

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).

My car has radar guided cruise control and it's amazing to use on highways and long road trips.

Agreed, this is the only really valuable driver assist feature. It’s the only one I really enjoy, especially the newer ones that work in stop/go traffic as well. I set it to 55km/h when driving in town, and then all I need to do is point the steering wheel in the right direction. I love it, and will be something I look out for if I get a newer car.

The normal adaptive cruise control is also great on the highway, except when you use it on the N1 or N2 incoming into Cape Town, set it to leave a nice 3 car gap between you and the cars in front, and then idiots keep on pushing into the gap. On the Range Rover I now set it to the shortest following distance it will allow when heading in to Cape Town.

All the other features are crap, and I hate that I have to remember to turn them off each time I get into the car. Wish there was a way to permanently disengage the lane keep assist and steering assist etc, drive me nuts

Was thinking about the cutting in on the highway

My thoughts exactly. When doing a long drive, the best way to stay alert is to drive more “actively”.

When I used to do a lot of cross country driving, on long boring stretches, I would often turn off the cruise control, and actively accelerate, decelerate etc, or when I the road is very quite, purposefully criss cross/weave my inside wheels between the dotted lines in the centre of the road. That keeps you alert.

Other issue with lane assist is on empty country roads at night, it’s good practice to drive straddling the centre line, giving you options to swerve left or right to avoid obstacles in the road way/animals walking into the road etc.
 
I intend to steer clear of anything made post 2022ish. Euro 6 has ensured most of the crap is hidden behind anti-defeat devices and is programmed to always activate on start up.

I was gobsmacked to find my bike's front radar applying the brakes mid corner while cranked over (37deg-ish) and closely following the bike in front through a mountain pass. This was with the ACC and most of the crap switched off of course. Seems there is always some level of front collision interference at play. Perhaps it only goes off in the full Dynamic Pro mode.
 
Nice to have but when you aren't paying attention and there is a phat pothole in the road, there is going to be kak.

Luckily with my car Toyota all those things are off by default and need to be turned on manually if you want them engaged (i never use the lane keep assist). Agree with driving on the N2, even with the nearest following distance, people will dive into the gap...
 
Who the hell calls Adaptive Cruise Control irritating? It's the best thing to happen to cars in decades. I wouldn't buy any new car that doesn't have at least that.

Followed by Blind Spot Monitoring which is just as useful day to day.

Lane assist and all that stuff can be annoying at times if you are on unmarked roads or something under construction, but it's never an issue long enough to go turning it off. The one that is debatable to turn off is the lane centering assistance, I wish I could just customise that to say where it should slot itself into a lane.

Rear collision auto-braking is the only thing I turned off on my car as it was triggering for bullshit all the time, so not it just beeps.

Sounds like you haven't actually used it and you are just making things up in your own head.

If there are no lanes it simply disengages....but it works perfectly find with even the most faded lines.

The only time it will get slightly weird is where you have roadworks and traffic diverted such that you now have the line in the middle of the road and then it will try to adapt.

Regardless it's not like it will just do what it wants, you remain in full control of it and if you hold the steering wheel it's not like it will override your input.

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...?
