Highway Driving

I've always enjoyed driving, and I've done a lot of it. Since October I've been driving to work and back from London to Stratford five days a week. I guess I've noticed some differences about the old highway 4 and 7 route compared to what I'm used to, more specificity the drivers on it.
The first thing I noticed when driving to Stratford, more specifically on the highway 7 part was the speed. I did my typical around 90-95 in an 80 zone at first (you need at least 15 over to loose points) and almost immediately I had a line up of cars behind me. I thought it odd at first but it happened consistently. Now I find myself doing closer to 100 in large packs more often than not and still being passed by a fairly occasional car/truck. And here's the kicker, no speed traps! I have barely even seen an OPP on the highway, accept when there has been an accident, which is barely ever.
So you must be saying to yourself wow! The perfect highway! Well that's what I thought until winter hit. I think some of the locals having been raised in the snow belt have become so immune to the snow they just don't notice it or something. The winter conditions have seemed to separate the drivers into categories somehow like a filter. And there is no in between categories, everyone seems firmly seated in one category or another.
extremely Cautious / Slow Dude - This guy does 20 with his hazards on with hands at ten and two in less than an inch of snow. This one is very rare but does exist.
Cautious but Realistic Dude - This guy drives 10 or more under what would start to be dangerous depending on the conditions, keeps a somewhat realistic distance behind the next dude, and seems to at least have a good grasp on basic psychics. (Especially coefficients of friction).
Penis Truck / SUV Dude - I've used to find these dudes entertaining, but now they just seem annoying and dangerous. Big engine, gigantic car, 4 wheel drive, huge capacity, sometimes double axle, never more than a tool box and brick in the back, with a sticker of Hobbs peeing on a brand name other than theirs, and a cigarette butt flying out the window every 5 minutes.
The last category seems to exist in abundance lately, tailgating really closely but not passing, (sometimes I wonder if they can see me over their hood), and when they do pass they swerve and cut me off only to do a speed slower than I was originally doing, or pass only to slide through the intersection ahead, I could go on and on with stories just from the past couple weeks. Not to get too stereotypical but it's like driving with a bunch of American suv's on the 401 but single lane.
Anyhow my frustration led to the crudest drawing I have ever created above. I always thought it would feel good to fling something at the tailgater behind me, and an egg seems appropriate. Of course there are lot of other items that would work. Feel free to post your amo suggestions!
