EV9 self driving in stop and go traffic, is it smooth or jerky?

Looking at the EV9 and wanting to know how it performs when in bumper to bumper traffic. My current car has Intelligent Adaptive Cruise Control which is great while moving, but if I use it in traffic the car is constantly punching the gas and then slamming the brakes. It’s horrible no matter what distance or eco settings I change.

Does the EV9 perform the same way in this traffic? Or does it smooth out the ride so you’re not constantly lurching?
