Trucks are what scare me most, they go right up behind me, and sit about 3feet off my bumper at 90km/h, and because they are so close, they can't see when my brake lights come on. I push the brake pedal so the lights come on for tailgaters, and if they don't back off, I start slowing down. My record is slowing down to 40km/h so the following distance was safe, turned out that guy was even towing. I think my first ecomod will be a "SLOW VEHICLE" sign on the back of my trunk.
I've decided I'm going to start filming my drives, so I can look back on what I'm doing well/not so well, and then when I see really scary things, I can contact the cops (who are open to driving complaints from the public).
