Hate to say it, but this is nothing new. I drove a semi 25 years ago on I-90 and people did it back then. I have had it in my pickup, especially when pulling my race car. It always amazed me what people would do around a vehicle that has a long stopping distance.

My new Ram has the blind spot warning lights in the mirrors too, but mine work very well. I still won't pull over until I can see the vehicle in the inside rear view.
