Summary Box: Apps to curb texting while driving

WHAT’S HAPPENING: Startups are trying to help drivers break the texting habit with applications that block phone functions in a moving car.

WHAT’S AHEAD: Systems that are specifically designed to deal with the problem and connect to a car’s electronics system might work better.
