LKAS at slow speeds

[Expatman]

Probably a silly question but do you have the option of operating the cruise control as a simple cruise control where the driver sets the speed and only the driver can adjust the speed or disconnect it. i.e a manual rather than automatic system. I use the manual system on my current car all the time in towns, rural roads and motorways and have never missed having the car think for me! I am the driver after all and am responsible for the speed, direction and safety of the vehicle. I can’t see a court smiling kindly on you if your defence was that “it wasn’t me m'lord the car was in control" !!

No, but you can drive the car on the limiter that way. It does need you to press the accelerator about half way, though.

Much as I like my Jazz, the ACC is definitely inferior to my previous car (Golf) with its radar based system. I haven’t experienced any sudden decelerations but even on a clear road the system seems to “hunt”, i.e. you can feel power being applied then released then power again. The Golf was much smoother.

I've noticed similar, you can feel it speed up and slow down. My Civic was smoother as well.

Unfortunately not, that would be my option as well.

However, I've driven a few times in the M4 average speed zone using ACC, so I don't accidentally speed up, and I've only had one 'incident' when I passed through a centre lane owners club lorry to overtake. I've never had any issues when I've been in lane 2 overtaking lane 1 vehicles.

In my last car you could easily switch between normal cruise control and ACC but it’s not an option on the Jazz

Actually it might be a defence if someone isn’t expecting the computer controlled steering ‘assist’ and if it drives you head on into oncoming traffic on a narrow country road!

These systems are on most new cars (Dacia has said they’re not interested in adding stuff just to get points towards a safety rating though) so I expect we’ll see adverts for lawyers soon.

Volvo has said that if the car crashes with their ‘self-driving’ active, then it’s the cars fault:

I had a chance to play with ACC yesterday on a motorway, including long sections of speed controlled road works. The ACC behaved as it should, including while passing slower traffic. I have to say though, my right foot was hovering above the accelerator pedal while I was using it so I was ready for unexpected braking. Could it be that the software has been 'tweaked'?

I don't know.

I've used it enough times now to know it's not for me so LIM it is in Specs zones, LIM works well.

If traffic is light enough I will use ACC, even through protracted roadworks, taking advantages of its features. (under my overall control)   If I think the applicable speed limit is too high for the current circumstances ,such as poor weather or increased traffic I'd probably switch ACC off, or at least set a lower speed.

LIM is useful  when ACC is not appropriate  but you have to maintain your speed manually.   Personally I dislike the stifling sensation on the accelerator when you hit the limit. I usually dial in a couple of extra mph, but drive  to the actual limit manually. That way the limiter only intervenes if I am speeding.

I find ACC and LKAS work well for me, although ACC is a bit sharp on acceleration and braking, even in Eco mode. 

However I only use these features selectively depending on conditions.  Like His Lordship The Magnificent Voltermore, I use on motorways only.   

if conditions are busy, I pull over to truck speed and continue to use ACC and LKAS.  What I cant tolerate is RDMS.  its just not been properly developed as far as im concerned.
