What's unsafe about radar cruise plus lane keep? People act like Tesla is shipping cars that fling themselves into pedestrians at every opportunity. Somehow we all manage to absolve the auto maker when someone with cruise control set on their 1998 Mazda rear ends someone on the freeway. Let's judge Tesla for autonomous safety when they produce an autonomous car.

What's unsafe about radar cruise plus lane keep?

It takes longer for a driver to react to a problem in that mode than to react without it.[1][2] There have been full-motion car simulator and test track studies on this. Even with test subjects who are expecting an obstacle to appear, it takes about 3 seconds to react and start to take over vehicle control from lane keeping automation. Full recovery into manual, where control quality is comparable to normal driving, takes 15 to 40 seconds.

There are now many studies on this, but too many of them are paywalled.

I am not sure why this tech is acceptable, at all.

People fall asleep even while actively driving the car. How can they be expected to maintain vigil with something like this.

But I guess Tesla is content with ending their responsibility at "Informing the user that they should be vigil at all times, even when car is driving itself", with out considering how feasible it is.

Another funny thing about it is that, earlier, with regular cars, you only had to watch the errors from the other drivers on the road. Now you have to watch other cars and also mistakes made by your own car's AI...

What could go wrong?
