Good point Dana. That type of thing can be alarming to newbies and veterans alike if not prepared for it. Even on an interstate highway cambers can change. Some are cambered toward the center median strip. This can create an unexpected thrill at speed especially when you pull out to pass a tractor trailer and have that wind blast hit you at the same time the camber changes. We always bring this up when a new sidecarist goes through our limited training here at the shop.
