Same idea with the newer (but still old) radios with 16-channel rotary switches. Your most important channel was programmed in both the Channel 1 and Channel 16 position. In the dark or high stress situation, you just turned the know to full stop in either direction and you were good to go.
That works well. On my trunked system, the users primary channel is #1 slot up against the stop. Slot 16, up against the other stop, is the emergency talk group. Just twist the knob one way or the other. 99% of users, that's all they need.
On the mobiles, ignition switched power and minimum volume levels set prevent a lot of service calls. Good old Bob "forgetting" to turn his radio on, or someone cranking the volume all the way down and forgetting is no longer an issue.
Home buttons on ham radios were always nice. Especially on mobiles where you didn't want to take your eyes off the road.
Some of these features are a bit more popular on the commercial stuff. I'm totally happy with my 20+ year old CDM mobiles with replaceable button caps.
