Their campaign has run smoothly. The numbers all point in their direction. And they have been helped, no doubt, by an astonishing series of mess-ups from their opponents.
Will was ejected from the vehicle and suffered fatal injuries. He was airlifted to St George's Hospital, London, but died three days later.Ms Radford, from Horsham, said passing his test just three months after his birthday "felt too fast".
"He wasn't experienced in driving on rural roads" she said, "and he was carrying a passenger, chatting to his passenger, and I feel his death could have been prevented."Ms Radford said her son "was a lovely, big-hearted boy, he was kind and popular and intelligent".She added: "He was the kind of son you could be very proud of. He was also an organ donor and his organs went to four other people."
At the conclusion of his the inquest into Will's death in March, senior coroner for West Sussex and Brighton and Hove Penelope Schofield, wrote to the Department for Transport about her concerns that there was a risk that future deaths could occur unless action is taken.Mrs Schofield said: "I heard evidence that where an inexperienced driver has a distraction of another young person in the car this can increase their risk of having an accident.
"In my opinion action should be taken to prevent future deaths."
Ms Radford said graduated driving licences would mean new, young drivers avoid distractions and the temptation to "show off".But in general the price of services, such as theatre and concert tickets, education and health, rose faster than goods.
The cost of housing, including rent, which is calculated under a different headline figure, also rose sharply in the year to November - up by 7.8%.But air travel saw its biggest November price fall since the start of the century.
Prices are almost always rising a bit; around 2% a year is considered a healthy rate of inflation.Much lower than that risks people delaying purchases because they may get cheaper. A little inflation encourages you to buy sooner - and that boosts economic growth.
