Another thing that most people don't seem to realize is that the lighter vehicle is much easier to control in a skid, since it has less enertia. I can throw my 2100lbs Honda civic hatch into skids and recover from skids on icy roads all day long with no problems, but if I got into a skid in the Isuzu Trooper and F-150 that I have owned in the past, I was pretty much along for the ride. Skid recovery in these heavier vehicles was more a matter of luck than control. When driving my Civic on icy roads, I can see vehicles around me skidding our of control into the ditch and into each other, whereas when things get a little squirrely on a slick spot, I can easily recover and keep on going. I typically can travel at least 10mph faster than the typical heavier vehicle on black ice with complete control. It gives my a perverse pleasure to watch when the SUV (EGO-mobile) driver I have passed tries to match my speed and spins off into the ditch.
