Like all Americans, Clark was saddened to hear about the terrible train crash in California that looks like it happened because the operator was busy texting instead of monitoring track signals.

When Clark commutes, he's shocked at how many people around him are texting or e-mailing on smart phones. He too was guilty of reading e-mails while he drove until he heard about the train crash. However, he was never crazy enough to try texting while driving.

After all, a car on the freeway travels about 25 yards in just one second. That's a sobering thought.

Nothing is so important that you have to text or e-mail about it while driving. But if it simply can't wait, try Jott.com. This service used to be free, but it now costs $3.95/month. Jott allows true hands-free texting and e-mailing with voice-recognition software that types your message for you (and sends it) as you speak.
