FM is an extremely wasteful way to encode signals intended for human ears. It would take a very incompetent set of engineers to come up with a digital standard worse than FM. Alas, they succeeded in doing just that and saddled us with DAB.
DAB+ is a reasonably decent if not exactly cutting edge implementation of digital radio though. If you spent a comparable amount of money on making a DAB+ network like what was spent on the FM network over the years, you would get flawless reception and wonderful sound for the same amount of channels.
What happens instead is that DAB+ is underfunded and the bandwidth overcrowded with way too many stations. Many of them have to even fake stereo! The signal cuts out way too often because the transmission power is so much lower.
Just say screw it and stream. But who has a car radio for streaming that is as easy to use as the FM ones are?
