DAB is the only thing that works reliably here
FM is almost useless, 3/4G mobile drops out if you move your heard - never mind the car.
DAB has the odd blank spot on the road, that's all, but never garbles.
DTV is messy: lost BBC4 HD in March, and it looks like the only way is an even bigger aerial.
Of course, this may be because I live in a very out of the way place called Basingstoke (someone has to)
I can *see* the local transmitter (Hannington) that FM, DAB and TV comes from.
BTW, El Reg: "FM already uses MPEG audio" (I paraphrase for brevity). WTF??
DAB is not perfect, and it's always a problem when you are an early adopter as the BBC was, but for the vast majority of current use it does seem to beat the others.
