Flicking to the next song whilst driving - if you dont see any particular danger in that it may be worth having a look at this recent event in the UK.

Family killed by a truck driver doing exactly this, including dashcam footage showing how quickly this happens if you are distracted for even a tiny amount of time. Very scary.

Timing at high speed has a lot to do with it, and lots of things can distract drivers from the road but the margin of error is slim here and so it seems very reasonable to legislate against this.
