Changes

Since nearly all the motorway networks lead towards London, you probably might have to go through that urban area somehow to reach your destination. The M25 is the ring motorway that surrounds the city and connects with every possible motorway network in all directions. It's recommended to find a lift past London as it's somewhat hard to find somebody going off the M25 in your direction from any of the service stations on the M25. Be careful: there are only 3 service stations, and the entire western section has none at all. It may also be possible to head around the M25 from junction to junction. However, the only problem is that a few of the junctions are really bad in the south, and you can get really stuck as a large part of the traffic is only going round the ring a short distance. If if you do get stuck, try making a sign M25 east or west. So consider waiting for a ride that actually takes you to the road you want to be on, rather than just stopping somewhere at random on the M25.
