linkI think it is fair to say that 21% of young drivers are not on the phone at any time.
So if that statistic in your article is correct Tone, then that data would go a long way to showing that the use of phones has a considerable detrimental impact.

1.1 per cent of car drivers, 2.2 per cent of van drivers and 1.0 per cent of lorry drivers were classi?ed as using hand-held mobile phones while driving in September 2008. The respective ?gures for hands-free phones were 0.5 per cent, 0.8 per cent and 0.5 per cent.
This largely confirms that 21% of young drivers indeed aren't on the phone at any time - indicating the use of HH really is over-represented.
HOWEVER:"Road Casualties Great Britain 2008" states that 16 of 2170 fatals had being on the phone as a contributory factor, less than 1%.Of course that is for drivers of all ages, and I don't know if either document differentiates between hand-held and hands-free.
The figure of 21% really doesn't work (even for specific ages within the group)

"Road Casualties Great Britain 2008" states that 15 of 1935 fatals had being on the phone as a contributory factor, again less than 1%. RCGB2009 wrote:
Since the last survey in September 2008, the proportion of drivers observed using hand-held mobile phones whilst driving increased from 1.1 per cent to 1.4 per cent for car drivers, and from 2.2 per cent to 2.6 per cent for van and lorry drivers.
There has been a 20% increase in HH mobile use over that year, so we would expect the rate of that contributory to increase by the same amount if HH mobiles really were such an issue. However, over the same time period the fatality tally involving HH mobiles had actually reduced. Of course we have to be careful of temporal noise and other variables (improved occupant protection).

The telephonic survey conducted in June on 1,004 adults affirms that many Americans get distracted by using their smartphones to call or text while driving.
The RCGB2009 performed the same kind of survey, reporting over 30% for HH mobile use. Clearly the perception of the public is somewhat distanced from reality.

There is also growing evidence to suggest the use of mobile phones is becoming a more common contributory factor in many serious collisions.
RCGB2008: Mobile phone contributory factor, for SI accidents = 60
RCGB2009: Mobile phone contributory factor, for SI accidents = 55
RCGB2010: Not yet released
Now that I've dug a little bit, I can see there is a lot of misrepresentation regarding the impact of mobiles whilst driving.
Let's have real data!
