This is more true than it can seem at first. For the GP's point, adaptive cruise behind a car slowing to turn can cause unexpected braking and startle drivers.

Adaptive cruise around sharp corners exposes the current limits of self-driving car vision. These systems usually have a cone of vision in front of the car, that only sees stuff moving 25+ mph in the same direction. Once a leading car is too far around a curve, the adaptive cruise can lose track of the leading car and accelerate sharply.

Some adaptive cruise systems intentionally don't accelerate while on curves, likely for this reason.
