While I'm figuring out what's the best and cheapest method for me to move around Iceland I came across Car pooling which sounds very interesting. To cut a long story short, you share a car with someone who has one, and split the expenses.
The Wikivojage page suggests using Samferda in order to find rides. The site is quite minimal and I'd like to know what are the best practices to arrange a ride. I browsed a few requests and no one talks about, for example, how much money it is customary to pay a driver, what happens if there are multiple stops during the trip, that take up time etc. Do I have to call each of them and arrange a deal?
How does this car pooling work?
