Parents are have done it.

And, teenagers, well…  enough said.

Texting and driving is rampant – and downright deadly.

It seems people can’t be bothered to take their eyes off their BlackBerry or iPhone – even when they’re speeding down the highway at 65 miles-per-hour.

Well, now they can – thanks to an ingenious app called iZup.

Call it a digital cure for lack of common sense.

Created by Illume Software, iZup uses GPS to calculate your speed – and whether you’re driving. If you are moving faster than your feet can carry you, iZup automatically locks out calls and text messages. That means incoming calls go to voice mail and text messages are held in a queue until you come to a stop.

Will iZup work in stop-and-go traffic?

Probably not – and your mobile device will still remain a deadly distraction.

Still, though, I give the makers of iZup an eager round of applause.

The open Web has birthed many brilliant products and services – but THIS, this is what we’ve needed for a very long time.

A full version of iZup will be out in December, but for now let’s hope that dozens of other software companies are scrambling to put out their own similar nanny-ware third-party app.

There are thousands of obscure, obscene, useless apps out there.

Why has it taken this long to produce an app that can curb such a chronic addiction?
