DAB is useless because : FM audio quality is enough (actually the bottleneck is the digital compression used in radio studios) ; the FM spectrum isn't saturated ; FM receivers are simple and cheap, it would be absurd to force people to buy new receivers and trash their fully functional radios. An important part of FM listening is in cars, and a lot of cars have custom proprietary radio trays or proprietery interfaces for hand commands buttons. Signal degradation is progressive in FM, but very irritating in DAB.
