Edit: plenty of the other rules outlined would rule out hitchhiking

It is definitely possible to hitchhike with the rule of not walking more then 500 meters. Sounds like a cool game by the way! I loved hitchhiking with arbitrary rules, an entire continent becomes a playground.

Having read the rules, I do believe is is possible to hitchhike in such a way that it qualifies as free transportation that allows to travel the longest distance. A simple way to do so it to get a single ride that is several hundred kilometers long.

The author of the question on StackExchange accepted hitchhiking as a valid answer.
