Speeding?

A woman was driving down the highway about 75 miles anhour, when she noticed a motorcycle policeman followingher. Instead of slowing down, she picked up speed.
When she looked back again, their were two motorcyclesfollowing her. She shot up to 90 miles. The next time shelooked around, there were three cops following her.
Suddenly, she spotted a gas station looming ahead. Shescreeched to a stop and ran into the ladies’ room. Tenminutes later, she innocently walked out.
The three cops were standing there waiting for her. Then,without batting an eye, she said coyly, “I’ll bet none ofyou thought I would make it.”
