Get tough to drive out 'careless' motorists

In the hands of an idiot, a car is a deadly weapon.

We've come a long way in trying to keep idiots off the roads, or at least make sure they behave behind the wheel. Many countries have tough penalties for reckless driving or driving while under the influence of drugs or alcohol.

But what about distracted drivers, those who stare at their smartphones or tablets instead of watching the road? Today, they have become just as much of a menace as drunks and junkies.
