My driving formular

I've derived a new equation;
Longer journey or distance(J) on road = higher risk of getting into an accident.(A)
The slower you get to destination(time, T) = higher risk of getting into accident.(A)

Therefore;
Shorter journey(J) or time(T) = lower risk.

If journey(J) or time(T) increases, (A) increases
The reason why people speed is because they want to get to their destination at quickest possible time so as to minimise the risk of getting involved in an accident.

To decrease (A), you'll have to either shorten the journey(J-1) or get to destination at quickest possible time.(T-1)
