Previously, no speed limits were set on drivers in Bravia, and it was left to the discretion of the Bravian drivers to drive prudently. In 2005, in an attempt to reduce instances of speeding and thereby reduce speeding induced fatalities among the Bravian drivers, the government introduced speeding limits. Such fatalities have reduced significantly since the introduction of speeding limits. However, data from traffic cameras show that the proportion of drivers who were driving their vehicles at high speeds is not lower than that before 2005.

Which of the following, if true of Bravia, most helps to resolve the apparent discrepancy?

A. The proportion of cars being driven on the roads post 2005 is not the same as prior to 2005.
B. The proportion of people using seat belts and air-bags, proven to be effective safety measures, has increased significantly post 2004.
C. Speeding is higher among the younger set of drivers than among the older, more cautious ones.
D. Most people find it very hard to give up their old habits of speeding even when faced with regulations restraining them from it.
E. The number of miles driven per car on average is no lower than it was prior to 2005.
