Systems and methods for efficiently addressing technical and privacy/authorization obstacles associated with tracking of individuals in a vehicle, and enabling route-based analysis to determine driving behavior, socio-demographics, future profitability, and interests of individuals or self-driving systems. Driving information is collected using a device associated with a driver and a vehicle or using data collected by systems of self-driving vehicles.

The invention discloses automotive color-changing glass. The automotive color-changing glass is prepared by adding a compound of silver and halogen and trace copper oxide into a common glass raw material, wherein the copper oxide is a catalyst. The principle of the color-changing glass mainly depends on a special chemical reaction between the compound of the silver and the halogen as well and the trance copper oxide and ultraviolet rays.
