Unfortunately, the vast majority of people doing it are never spotted by police officers. I walk to work most days, and I can't remember the last time I didn't see at least one person (usually it's at least half a dozen on a 30 minute walk) texting while driving.

This morning, as I dropped my daughter off at school, some woman pulled off from the side of the road and drove about 30 yards before bothering to look up to see if there were any kids crossing.
