I hitchhiked a few times and discovered half a dozen techniques to increase the probability of getting a ride in less time (though time is relative when hitchhiking).
I was wondering if there is a resource on the Internet with a good list of tips to improve your chances of getting a ride and arriving at your destination as quickly as possible? (By quick I don't necessarily mean getting a ride from a Ferrari going 200Km/hour but minimizing the changes between cars, etc).
I can imagine some tips are "universal" and others may vary from country to country. Both are welcome. If the resource has some security tips that is also a plus.
