Really? Um in good signal areas it does but near to big buildings and
hills I notice that they tend to descend into boiling mud mode then
switch to another station.

If you drive round a town with large high buildings deeply packed
together, and the FM transmitter some way off, you first get it switching
to mono then the signal fading. Centre of London ideal for this. DAB is
for some reason rock solid. On the stations I've listened to while trying
this.

With fm its the his and multipath distortion and weird whistles and
burbles that go up and down, often going back to mono gradually or abruptly
depending one supposes on the receiver design.

I ride in a lot of private hire cars and notice such things.
Very few have traditional aerials, many have the rubber duck and some
still use window heater aerials.

Given how much my aftermarket DAB aerial cost, I'm not sure a car maker
would pay that much. Aerials built into the screen are more a design thing
than the best performing.
