I've been putting in the road miles for over 28 years now, only been hit once. I've hit a couple cars with my bike though, but that's 'cause I was riding like an asshole. Now that I'm a grown ass man I choose my routes a bit more carefully, I don't really enjoy "playing" in traffic the way I used to.
Twisty descents are pretty rad on the road bike, you can go scary FAST, particularly with a stable handling bike and big fast tires and on a lot of roads you can outrun the cars. I run 46cm Nitto Noodles, 28mm light tires and carbon wheels and steep, twisty descents on smooth or rough pavement are freaking awesome. I bet Whistler has some awesome descents.
