TWC: Texting while cycling?

Here's a new one for ya: Texting while cycling.
On Sunday, a guy was in my bike lane coming toward me. He was clearly trying to text someone on his phone. The same thing happened Tuesday. Not sure if it was the same guy or not.
BUT: Come on, people!
Both times, I had to yell for the person to look up then swerved.
My husband said later he hoped he hit a tree.
It's dangerous enough to text behind the wheel of a car.
It's also dangerous to hit someone head on going 15 mph on a bicycle.
