I actually knew about this one going in, since it's been a requirement for a bit longer. My Hyundai has two modes, one where it simply beeps if you cross the lines without the turn-signal and the dangerous one where it locks the steering wheel.

Only the slightly annoying beeping one seems to be mandatory, the extremely dangerous steering wheel locking one isn't. Otherwise I wouldn't have bought the car at all.

Steering wheel lock? Is that seriously a thing, or is that a strong exaggeration?

My car just gently applies a tiny bit of force on the steering wheel, to keep the car in the lane. It's very easy to override manually. In fact, it feels quite similar to moving out of pretty shallows ruts in te road, and could even be mistaken for it.

No, it will actively prevent you from turning the wheel if it means you will go outside your lane. It does have threshold if you struggle enough, in which case it will simply undo the lock and you get to jerk the wheel dangerously in that direction.

If you use the turn signal it won't lock the wheel, but if child suddenly runs into the road and you will try avoiding a collision, you'd better remember to use the turn signal first.
