If you can't drive responsibly with a baby on board lane assist isn't going to save your ass. If something happens to your baby which distracts you ask someone else in the car to take care of it, if there is nobody to help pull over at the earliest opportunity.

Lane assist will not save you from anything else but lane departure and there are a lot of other things that can go wrong while you allow yourself to be distracted because you rely on lane assist to keep you safe. That's not the intended use of this feature.

Also I find it interesting how much you assume about a person or situation from a single word.

I absolutely agree. There is absolutely no excuse for the driver to take their eyes off the road to assist a baby in the car. How would you assist a baby in the back seat while driving with a seat belt on anyway?

As I read about people using these features, I'm convinced they shouldn't exist. Yes, crazies will apply eyeliner while going sixty on a highway but I doubt driver assist is an adequate solution for such stupidity should a driver poke themselves in the eye.

If you have ever driven with a baby or child in a car you will have learned that they can cry or make a tantrum. Assist systems are intended to supplement and assist the driver in situations of increased stress. The idea that one would actively take their hands off the wheel to do something with a child is so preposterous ghat only commenters on HN could seriously suggest that.

You seem really defensive about a pretty inoffensive remark. Maybe you need to reflect on why you are so angry about something so trivial.
