Why use nitrogen for car driving as for airplane?

Advantages of inflating tires with high purity (over 95%)
nitrogen:
. Nitrogen is a type of inert gas, specially can keep
  tires in low temperature even after long time driving.
. table tire pressure, helpful to extending the life of
  tires and wheels.
. Reduce the tire noise and car vibration, so driving
  becomes more comfortable.
. Reduce the tire friction force and the fuel consumption,
  good for cost saving.
. Minimize the tire deflation risk and the tire broken
  danger.
. Enhance the vehicle driving controllability.
