Changes

In many places in the United States, on ramps are the '''only''' legal option for places to thumb. This includes the entire state of Tennessee. In all countries in Europe you can legally hitch on a slip-road leading onto the motorway, '''as long as you stand in front of the motorway sign.'''

In some countries the motorways or a part of them are toll roads, so the places where drivers stop to pay might be very good spots to get a ride, since all the traffic going your direction can see you. Other type of toll booths is only stopping the traffic joining/leaving the motorway on one particular exit, there the traffic will be much more weak.
