My first thought on trucks passing closer is that they are more likely to be male drivers. Up here "in the pickers" of northern Wisconsin, I've noticed an attitude among some men who like their hunting, fishing,etc. and prefer trucks, snowmobiles, boats and 4 wheelers. Their thought process is that they have to pay to register and use roads and trials and they really don't like the fact that cyclists don't have to pay to register their bikes to ride on the roads (we do have to on the trails). Therefore, they don't feel they should be on the road. I've heard more than once that said truck drivers will actually drive CLOSER to cyclists on the road to scare them.

Nice, huh?? On the busiest street in Wausau (Grand Ave) cyclists have to ride on the sidewalk by law.
