I need to check my setting as I can't think what the sensitivity is on tbh, but I'm going to guess its still not the same kind of technology as like you would get in a Tesla. I suppose though its not meant for that, its more to prevent you falling asleep and drifting into the next lane. Not for the car to drive itself...need to make sure you indiciate when changing lanes (as you should anyway..) as otherwise you will get some resistance when changing.
It's something I wouldn't pay £100 for personally even if it cost that much to add it in a factory order.
HBA on the other hand, I was using it last night and my passenger asked if I was turning the lights on or off or if it was the car. It might be a lazy feature, but its a very good one!
