The question isn't whether they're dangerous, anymore.
The question is, when is safety legislation going to be passed that prevents them from being used for any routine adjustments while driving. I.e. windshield wipers, AC, change volume, skip to next track, etc.
Like it's fine if you still use them to input a GPS destination, change long-term car settings, connect a Bluetooth device, etc.
But we need to separate out the actions routinely used during driving and legislate physical controls. Why is there not legislation for this already?
