As far as I know this was the first time a vehicle entered the front yard. I hadn't considered any liability issues with the metal posts, I was only thinking of making the front yard safer for my kids. Once the row of hedges I planted takes off, they will provide some stopping power. I guess I'll leave it at that.
OK ... here are some pics:
Right after the accident
I have to trim 6" off the posts and put caps on them that match my mailbox post. I'm going to let the western red cedar age to grey.
