This produces a weird effect when listening in the car and moving in-and-out of good digital SNR range. When the radio switches between analog and digital, unless the station has them perfectly synced (never), there's always a little echo or stutter. It seems like it would be nothing but it's quite annoying.

Particularly annoying while driving in very hilly areas, that's for sure. There are some traits of signal propogation that are very difficult to work around, even with buffering and error correction remedies.

It shouldn't be impossible to sync. Here in Europe we even sync FM transmitters so they can broadcast on the exact same frequency without causing interference! That requires a magnitude higher precision than this.
