i enjoy hitchhiking
First thought: I hope you're safe! Second: although typically "free", have you found that your rides come at a cost? We all know free is not always free...
I know and there are safety precaution on it all. What are you scared of? 
I'm not scared -- but what safety precautions? How do you know that the ride you're taking is safe? I know it depends where in the world you are, but there are very few places in the world where laws exist to restrict or regulate it.
And i am in that part of the world. And i mean you are scared something might go wrong. Have you ever heard of anything go wrong in the news before while hitching? 
Um....yes! But again, that's may be location. It's interesting that hitchikers in different parts of the world use different hand signals. Are you of the arm extended, thumb up variety?
Yes, i am of the arm extended, thumb up variety
In Africa, the hand is held still with palm facing upward; in Australia, they point the index finger at the road. Just in case you find yourself needing a ride in those locales ;-)
Okay. But i cannot do it in an unfamiliar country. That might be dangerous
Fair! And do you have a different name for it? Hitching, Thumbing, or Autostop?
