ACC/Tempomate in active curves

The following situation: 80km/h on city highway, a little narrower curve when changing to a crossing highway. This curve goes for the experienced driver at 80km/h, but most of them drive slower, because the curve is optically deceptive. It also goes up slightly. I found out the last time that the ACC (Skoda Kodiaq) takes away gas here. If I want to drive the 80 constantly, I have to give gas. Why is this so? I also tried it out in an empty parking lot at speed 30. As soon as I get a little rough, I have to drive the 80. The car no longer holds the 30th “stronger” but does not mean that other assistance systems are required, but only means normal fast cornering without starting slides. I don’t think this feature is necessary. What do you mean? And what does it look like with other manufacturers (outside VAG)? How do they behave?
