Front Driver Side Air Bag Inflator problems of the 2005 Audi S4

Takata recall. I received two letters from Audi in March 2017 and recently a third letter in March 2018 informing me of the passenger frontal airbag inflator problem. The most recent letter states that it is dangerous to drive and the airbag could explode causing serious injury or death. I called Audi service in April 2017 and again in April 2018 and they said they do not have a fix for the problem and have no time frame for when it will be available. How can I continue to drive a car that has significant risk to cause injury and they will not fix it for over a year?.
