I haven't tried at night yet, but until recently, TACC was useless on two sided roads, even during daytime. Did a back and forth trip last weekend with 2022.8.3 on 85 km of two sided roads with speed limit ranging from 50 km/h to 90 km/h. On the first 85 km, got just one slow down and one hesitation. On my way back on the second 85 km, two slowdown and two hesitations. Hesitation were climbing up small crest that were going down right after so the car couldn't see in front. Slowdowns where gentle, no abrupt braking. Roads were really curvy and hilly with some curves with speed recommendation of 40 km/h. Crossing traffic turning right on those curves created absolutely no braking. Things are looking better because last fall, it was painful to use TACC on those same roads.
