People are so rude! So what if he doesn't have the same experience  as someone not famous while hitchhiking. He never claimed he would. It's his experience not yours. He stated that it was about meeting and trusting people. Why do people always bring others down first chance they get and also if it's not something your interested in then just don't read it. Pretty simple.
