Traffic Junctions

There was this statistics student who, when driving his car, would always accelerate hard before coming to any junction, whizz straight over it , then slow down again once he'd got over it.

One day, he took a passenger, who was understandably unnerved by his driving style, and asked him why he went so fast over junctions.

The statistics student replied, "Well, statistically speaking, you are far more likely to have an accident at a junction, so I just make sure that I spend less time there."
