Not read anything about autohold locking up either.

If it did, such is life. If people want to honk, good for them. It will give me a better story to tell.

But, seriously, I do use autohold quite a bit. There are a few exceptions. If I'm first at a light and people start to walk across the walkway in front of my X5, I apply the brakes manually. In general, I'll also apply the brakes manually if the intersection in front of me is fast moving. That is, I'd not rely upon autohold to be the only piece of equipment keeping me and my X5 from being sideswiped by a large delivery truck. I'm quick, to be sure, but feet can slip, and attention can lapse.

It's simply unsafe, in my opinion to use autohold in many situations.

I think autohold is a great feature, but I'm not going to place my life or the life of someone else in the hands of BMW electronics (at least not in this regard).
