Are you allowing enough space in front of you for cars to merge in without wedging themselves in front of you? That's the worst problem I see around here -- cars in the freeway running bumper to bumper, and then a block of 3 or 5 cars also running bumper to bumper trying to force their way in, but none of the cars really leave enough room for a smooth merge, so the cars on the freeway end up hitting the brakes when the merging cars force their way in.
