Braking at any point is safe with a competent driver behind. There's a reason we know our stopping distances and don't follow excessively closely.

Alas half of drivers are worse than average.

I'm one of them. Yet I still haven't had a situation where "lane assist" or "front assist" has actually been a good thing.

That is unrealistic. If you expect the brake perhaps but the most competent thing to do in case of an emergency brake is doing nothing.

Not on a hard curve with oncoming traffic.
