And that source is... "Exit only" lanes and merging lanes.
Its true. I see it everyday. Lets say a 4 lane freeway. Lots of cars, traffic is slow, but still moving. The traffic jams start happening a mile before one of the lanes becomes an "Exit Only". Some people have to merge into the next lane, and some people don't realize it before its really late and slow down to change lanes.
Same deal with merging lanes.
