To the best of our knowledge, no existing carpooling proposal offers a quantitative method based on the theory of six degrees of separation to decide if two users should trust each other to share a car or not. Some of the proposals do not even allow drivers to decide who can or cannot apply their route. There are some proposals  that use a quantitative method based on the similarities among users. Their main problem is that they have to collect information about the attributes and characteristics of each user. The proposal aims to be simple for the user, so that he/she does not have to fill in any information about his/her attributes. With a simple click to enable social login on the network after a previous registration, the user can log into the system and start using the platform.
