Back in the days when the Mulsanne straight was straight,you could watch from beside the bar.It got a lot more crowded later in the day.The electronic signature of some of the cars seems to have been every bit as loud as their sound to judge from the way the videocamera of the day throws a wobbly when they pass.At 0:52 a car passes,14 seconds later you can still hear it when(@ 230mph)the car is 0.9 of a mile away.But as the sound takes 4 seconds to reach the camera from that distance, the car was only 0.64 of amile away when it went out of ear shot.(very roughly).   • Le Mans 88 Mulsanne
