'''Porte d'Orleans''', at the ''périferique'' seems okay, Metro Porte d'Orleans. There's a gas station, and a good spot (just under Novotel building) at the traffic junction to the "périferique extérieur". Don't go with cars going into the suburbs. The next tollway or gas station takes about 50 km!

 # The gas station at '''Briis-sous-Forges'''. Look at A10 section# Take a train to '''Rambouillet ''' from Paris-Montparnasse (about 7€) and start hitching on the N10 south, until the A11 entrance

 You can also go to # Another good spot, but way cheaper is '''Portes d'Orleans ''' (almost the same than for see info above - section A6 and A10) and have where you can hitch with a sign "Chartres" or "RennesA10"/"A11". If you get a ride to Péage de Saint Arnoult (from someone going to Orleans - A10 - for example) it's good, since it's before the split.
