We see many people who get into the merge lanes and are so busy talking on their cell phones that they don't realize there's a 42' motorhome next to them that can't cede the lane due to a vehicle in the left lane.
They just mosey along, chatting away with the phone to their ear and their elbow on the windw ledge.
Those drivers almost always put on their brakes suddenly when their merge lane is about to run out. I worry that they're going to try to merge in IMMEDIATELY after the MH and take out the tow'd.
