I'm struggling to see how you can be so calm about what you just said. To me, the idea of a system that works 99% of the time and doesn't work 1% of the time is utterly terrifying, far more so than a system that works only 50% of the time. 1% is small enough for a human operator to become complacent, but still many orders of magnitude greater than an acceptable risk factor. It seems like exactly the sweet spot that's going to maximise loss of life.

I guess this is about predictability.

I know what (and where) the problematic spots are for the lane-keeping, so I use it in situations where the benefit is large and the risk is manageable.

There are many places where I won't switch it on and just drive myself.

Also 99% vs 1% depends on how you look at it. The main road I drive is about 200km long, in one direction it does not have any problematic spots. In the other it has 2 lets say 10 meter spots. By distance it's 0.01% problematic. It's not like Desert Bus where it tries to get you all the time.
