M5 Flat Tire / BMW Roadside Assistance

Who here has experienced a flat tire on your beast and had to utilize BMW Roadside Assistance because of it? I had a blow out yesterday on one of my rear tires, the M Mobility kit was useless (but now I'm sure I have a wheel / tire full of useless sealant) and I had to call BMW Roadside Assistance. They were quite helpful in finding and sending me a tow truck to tow the vehicle to the local dealer but that's it. They basically said I was on my own as far as finding alternate transportation on a Saturday evening about 5 PM.

I don't know about you guys but I'm in a BMW M5 that is less than 2 years old and still under the original factory warranty I expected a little more than "we'll send the tow truck - good luck". I was about 50 miles from home on the side of a very busy interstate. Even if I had to pay for alternate transportation (which I was more than willing to do - afterall it wasn't BMW's fault I had an unfixable flat - just their fault that I had no spare tire) I would've like to have seen a bit more "assistance" in finding it. Am I asking for too much? Is this what I can expect when broke down on I-55 in the middle-of-nowhere Mississippi at 11 PM at night trying to travel between New Orleans and Chicago?
