* when the broadcaster screws up their RDS signal after a traffic report leaving you stranded on the wrong station.
* Or FM stations that run at different frequencies from different transmitters (this used to be a massive problem when driving long distances even just 20 years ago but now even the analogue car radios are digital devices that scan multiple frequencies to hop to the next frequency aired by a given station so you don't experience much cutout).
* Then there is the obvious issue of "dead zones" where the signals cannot reach (tunnels, some industrial locations, etc).
* Digital radio also suffers from frequent, albeit brief, cutouts while driving too but I've found that to have fewer dead zones than analogue.
* Bleeding used to be massive problem with analogue radio as well - this is another problem that was solved when radio started going digital.
So this is with 100 years of research and development into a protocol that requires an order of magnitude less bandwidth and yet most of the improvements have only been in the last 20 years when things like RDS (digital packets in analogue signals) and DAB have been introduced. Given that IP streaming video content isn't that far behind, just imagine how good it is going to be when that technology finally matures.

Wait, is this really a common thing? How would I know if a car radio does this, because I'm 99% sure my car doesn't.
The name of the feature is usually AF (RDS), all my car radios since 90s have supported it and all multi-transmitter FM stations here make use of it. I'm in Finland - no idea if it is less common in US.
Maybe it's not a thing any more? Or maybe it's not as clever as scanning multiple frequencies? I've not listened to analogue radio in the car for long distances in a while but I do remember there used to be a big problem with national radio spanning multiple different frequencies and your signal would drift out as you changed regions. This problem seemed to solve itself when RDS and "smart" radios started becoming a thing. However my experience is with video broadcasting rather than radio so I might have gotten some of the details wrong.
