It's hard to believe a car exists that ignores steering input. I suspect you just didn't try hard enough. Perhaps because it was a last-minute decision, you weren't very confident it was safe to change lanes and chose to give up some decision making to the car?

Youtube will tell you that bumping into someone sideways at highway speed can leave either car spinning and flipping off the road.

Oh, I suspect you can overpower it, if that's what you mean. However, if you weren't expecting it'd do something like that in the first place, it can accomplish a nonzero change to your trajectory before you intervene.

Believe me or don't, but, if you operate a vehicle with these assistive systems, I encourage you to carefully familiarize yourself with the ways in which they may unexpectedly affect its behaviour.

Of course there'll be some effect but your reflexes are doing a closed loop control system with the trajectory of the vehicle as input, so you'll automatically overpower stuck controls without even thinking. If you're steering with your knees or your little finger, it might cause a crash but that would be thing not to do, not have lane assist behave differently.
