I see it multiple times every single day. I've witnessed accidents and been run off the road as a result of it.
Manual enforcement is always going to be tough, some areas still allow an easy loophole by way of claiming use of voice/GPS functions and even in cases where people are ticketed the fines are generally quite small.
This is a rare case where I'd be willing to consider manufacturer enforced controls.
