Doesn’t RDS mostly solve that for the most common case where frequency changes becomes an issue (car radios).

Yup, and DAB also still works.

Umm mostly. IMHO DAB is a failure, at least for vehicles.

I listen almost exclusively on dab in the car. It auto fails to FM but it’s rare I go somewhere where that happens.

It’s probably highly variable depending on location and the quality of your radio/antenna. It’s useless where I am.
