Do we need assistance while driving? While some people believe we can't do without it, others disagree. A recent internet blog entry read: "You can just forget the rest. If you know how to drive then you don't need that kind of stuff! Didn't need these kind of gimmicks in the '70s, don't need them today." Yet recent research has shown that driver error is one of the most common causes of traffic accidents. Matthew Beecham reports on how these gimmicks can provide a helping hand in times of trouble.
