The Z-300 is a particularly fast new sports car, popular among young drivers. It is an expensive model, and relatively few are on the roads. Two months ago, seven different young people in Catoville were arrested for operating the Z-300 at excessive speeds on local roads while having a blood alcohol level well above the legal limit. Since then, a police watch group has reported that Catoville traffic cops frequently have been pulling over drivers of the Z-300 and testing them for alcohol: the total number of Z-300 drivers stopped and tested is five times greater than the total number of drivers of all other makes or models stopped and tested.

Which of following conclusions can most properly be drawn from the information above?

【选项】Drivers of the Z-300 exceed local speed limits by much higher margins than that by which they exceed highway speed limits.
