flat with a run flat -- I want to hear your experience!

I live in L.A. where potholes are ubiquitous. I hit a big one a few weeks ago (with my previous ride, a 07 335i w/sport pkg) and 2 days ago, my flat tire warning light came on. This happened before and it was just sensor error so I continued my commute to work (about 25 miles). A couple hours later, after the tires had a chance to cool, I drove to a gas station to take a cold temp read. When I got there, I noticed there was about a 2-3 inch tear on my right front tire. I drove to a tire shop and it took $360 and about 3 hours (they didn't have the tire in stock and had to get it from a warehouse) before I was out of there.

I guess the lesson to be learned was I should always pull over right away if the tire warning light comes on and next time I hit a pothole, I'm going to pull over and take a picture of it. That way if I get another flat, city of LA can refund me.
