I love test drives!
To be exact, I love driving at breakneck speed if I know that I am not going to cause an accident. For those not familar with the basic test courses, there's usually four lanes to to a course with four different speed limits. The first lane: 0-50km/h; second lane: 50-100km/h; third lane: 100-160km/h. Finally, the fourth lane slopes upwards at a 45 degrees angle and the car needs a considerable speed to stay on that lane because of the angle. I love the 4th lane!
Actually, the first rule of test drives is not about breaking the sound barrier but to see if the car handles, drives and breaks well under normal driving circumstances. Of course, you are welcomed to test how the car handles at max speed but seldom you need to climb that 4th lane.
But at the test course, everyone will say that the rule is a whole load of bull. Of course you start a slow acceleration to see if it changes gears nicely; then you jam the breaks hard to test the breaking performance. You can test also the steering control and almost every features the car has. Five minutes tops, and then you start to fly on that 4th lane...! (^_^) v
