I love to use cruise control on most any road (local or highway) and really want to use it on on the ID.4. However, I've noticed something annoying: the ID.4 keeps fluctuating the speed, very slightly, so that it's oscillating between accelerating and regenerating every few seconds. I can certainly feel it, especially at lower speeds. I also brought up the Vehicle data screen and was watching the energy consumption display. I confirmed it would go up slightly, then go down, then go back up, etc. corresponding to the slight accel/decel I was feeling. To be clear, this is on a open road, not following another vehicle ahead of me (not ACC).
It's noticeable driving on flat terrain. Going uphill, the ID.4 is always expending energy, so I suppose it only has to adjust how much energy it's adding to maintain speed. And going downhill, it can just control the amount of regen. But on flat terrain, it is as if the software says, "whoa, you're 0.5 mph over the target, I'd better apply some regen to bring you back!" But the amount of regen is too large (large enough for me to physically sense) and for a too-long interval, so I end up 0.5 mph below the target. And then the ID.4 decides it needs to accelerate to catch back up to the target, and ends up overshooting on the high side. Lather, rinse, repeat.
I normally drive in D, but testing in B had the same result. And trying different driving modes (Comfort vs Sport) also had no effect. I think being in cruise control in general overrides all those settings as it hands control of regen to the cruise control software anyway.
The effect is less noticeable at, say 50 mph+, as the fluctuation in speed is relatively small compared to the overall speed. But I do use cruise a lot on my local streets, which are 25 mph. That's where it's most annoying.
I'm assuming this is just poor software, similar to the "why does the speedometer show 1 less than the cruise target." Unless I'm the only one who's experienced this.
