I can ride 30 miles with one brake and I did, but I would rather have not had to.
As I stated above "if you already have AAA plus" which most people I know who get AAA usually do for the 100 mile towing, then it can come in handy.
What if you break a few spokes while you are out there away from help? You could hitch back to civilization, it may even be faster, but to admonish the service based on the idea that you could get by without it is like saying you dont need antiseptics for a wound because you have a good immune system.
Maybe it's not worth paying another $60 for, but I didn't even know I had this service until I read it here.
