If GM were to go BK (I don't think they will and they will get gov. help), people will still buy cars - just from a different company. SIRI has agreements with every major car company. Who cares if more cars are bought from a different car company - as long as there is a sat rad in the car? How does the GM arrangement with SIRI compare to the arrangements that SIRI has with the other car companies? Maybe it would be better for SIRI if people bought cars from different car companies in which the revenue sharing arrangement was more beneficial to SIRI?
