Dodgy Statistics

It says here that "...research for Downing Street in 2000 estimated the number of individual crimes at around 130 million a year."

If we assume that 20 million people drive a vehicle each day, and briefly go above the speed limit once (on average) on their journey, then that's 7.3 billion individual crimes per year, just from speeding. And my numbers are probably under-estimates. So why is Downing Street's estimate only around 1% (or less) of the true number of crimes?
