OG10-CR-78 "regularly"

Q. A recent report determined that although only three percent of drivers on Maryland highways equipped their vehicles with radar detectors, thirty-three percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not.

The conclusion drawn above depends on which of the following assumptions?
(A) Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.
(B) Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.
(C) The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detectors.
(D) Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the report.
(E) Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.

正确答案是B，我选的是A 我把句子"drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly"理解成了"Usually, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit". Then I made it wrong.

Is there anything wrong with my logic?

或者是题目有瑕疵？

题干如下
尽管只有3%的车辆装有radar detectors，但是因为超速而被开罚单的车子中有33%的是安装radar detectors的
得到结论：安装radar detectors的车子的驾驶员更经常超速（相比于那些没安装的）

认为这个推理过程中间有跳跃
3%的车辆装有radar detectors，但是因为超速而被开罚单的车子中有33%的是安装radar detectors的
上述前提最直接推导的是 安装radar detectors的车子的驾驶员通常更经常被开超速罚单
而结论是他们更经常超速

因此补充这个推理中间的跳跃就是这个推理成立的assumption
那么就是：更经常被开超速罚单 代表 更经常超速   +。+！
即B选项

但是好像reguarly的句子可以理解为“安装radar detectors的车子的驾驶员更经常超速”，也可以理解为“一般安装radar detectors的车子的驾驶员更容易超速”一样

我当时就是这里理解成了后头的，选了A
