Throughout my military career, I often had the official additional duty of Unit Motorcycle Safety Coordinator. This gave me special access to lots of police and insurance reports.
Insurance report: Motorcyclist attempted to drive between vehicle and trailer. Vehicle and trailer was not parked. Report said motorcyclist stated he didn't think trailer was attached to vehicle.
First hand report from police officer in southern Illinois: Person loaded trunk full of groceries, got in vehicle, and promptly drove into side of grocery store. First statement by at-fault driver was, "I didn't see it." Person had parked outside grocery store and just finished shopping inside. Person managed to center-punch 60+ foot long by 16 foot high exterior store wall. Somehow they managed to "not notice the store" when they parked facing it before shopping and after shopping in the store.
People rear-end or center-punch 18-wheeler semi-trailers so often that it's not worth reporting individual cases. Truckers are well aware of these accidents and I've talked with a number of trucker who have personally experienced it. These truckers have mentioned how unusual it is for a semi-tractor to be traveling without a trailer. Likewise, they have a bit (very little) of understanding not noticing a flat-bed trailer but tend to be emphatic when saying, "How the hell does someone not notice a large enclosed trailer?"
Multiple reports of people -- on the road -- driving over small trailers like Lowes and Home Depot sells.
All this is why MLP has lots of lights and a switch that allows me to flash some of the lights if I think someone has somehow failed to notice the motorhome. (Now, if I could just figure out how to make Alaska moose notice my vehicles.)
