The invention provides a vehicle data analysis method that enables quantitative analysis of characteristics of vehicle data indicating transition in a driver’s driving operation, and a vehicle data analysis system using this analysis method. The system comprises a second elongated linking element, the connector being capable of being fixed simultaneously to both linking elements. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This scheme is particularly advantageous in communication systems with unreliable communication channels, e. The method permits the use of a display device with large pixel count, yet with high display definition and performance.
