There is a strange phenomenon I have observed over the years. Whereas there are vehicle drivers and drivers of vehicles, there seems to be some drivers who are driven by their vehicles and others who drive their vehicles. Those who are driven by their vehicles are usually overly eager, anxious and erratic. They also appear to have no regard for their own safety. Rather than control the vehicle power, the power of the vehicle controls them. These drivers blame their vehicles for a puncture or for a faulty fuel pump. It is a strange phenomenon, but you may be able to identify with what I am talking about. Those who drive vehicles are for the most part calm, confident and considerate of their own and others safety and comfort. There is a subtle difference between those who are driven and those who drive. That difference emerges in the cost of maintenance.
